项目简述：本项目采用“金属一步气化法”技术制备高品质透明电极材料ITO纳米粉体，通过对ITO纳米粉体的组织与微结构分析、制备工艺的优化，开发高品质透明电极材料ITO纳米粉体生产技术，使企业具备高品质透明电极材料ITO纳米粉体的生产能力，使高品质透明电极材料ITO纳米粉体的生产技术和产品质量达到国际先进水平。目前高纯金属铟的市场除作为焊接材料添加元素外，主要是销往日本等国生产ITO粉体。我国是铟资源大国，每年冶炼金属铟可达200吨，居世界首位。透明电极材料铟锡氧化物ITO（Indium Tin Oxide）作为一种重要的铟深加工产品，不具有优良的导电性和可见光透明性。其对可见光的透过率高达95%以上；对紫外线的吸收率≥85%；对红外线的反射率≥70 %；对微波的衰减率≥85%；同时ITO薄膜的加工性能极好，ITO膜层硬度高且耐磨耐蚀，因而ITO透明电极材料近年来在薄膜晶体管（TFT）、平板液晶显示（LCD）、电色层窗口、光生伏打器件中的有源和无源组元以及红外辐射反射热镜薄膜等方面获得了广泛应用。作为当今信息产业重要的电子材料产品，透明电极材料ITO以液晶显示、太阳能电池、固体电色（EC）器件、电磁屏蔽、雷达屏蔽保护和节能建筑为主要应用领域，而在这些领域对透明导电薄膜的性能要求也越来越高。高品质ITO粉体所制备的高性能靶材是透明ITO薄膜生产及决定ITO薄膜质量的关键技术之一。目前高品质ITO粉体产品只有德国、美国、日本等国家生产，我国尚处于研发阶段，还未形成产业。而我国一些大型玻璃产业公司，如“南玻”、“洛玻”等已建成数条ITO玻璃产品生产线，对高品质ITO粉体的需求也在增加，但其所用高品质ITO粉体目前还主要依赖于从国外进口；而在国际市场上，随着透明电极用量的急剧增长，ITO粉末用量也急剧增加。因此，高品质ITO粉体的开发在国内外都具有良好的产业前景。

项目在本地区的作用与地位：高品质ITO粉体的生产可有效改善目前云南省铟资源利用的产业链结构，加大铟产品的深加工力度，提高产品抵御市场波动的能力。

    作为我国铟资源的主要产地，目前云南省的高纯铟冶炼已初具规模，出现了蒙自矿冶公司、宣威金沙公司等以高纯铟锭为主导产品的生产企业，产量逐年提高。作为初级产品的铟锭，受市场供求关系影响，价格波动很大。1997年亚洲金融危机后，铟价格大幅回落，2002年为60美元/公斤；近年来，受全球铟需求量的大幅上升，供需缺口增大，铟价也大幅上扬：2003年达到600美元/公斤，2004年超过1000美元/公斤。短期市场行为导致的原料市场价格波动，要求企业提高抗市场风险的能力。因此，在现有以铟初级产品为主的生产基础上，改变产业链结构，将产品向下游延伸，增加铟深加工能力，是企业发展的重要方向。高品质ITO纳米粉体项目，旨在改善我省目前铟生产产品单一的状况、加大我省铟深加工能力、加大我省高新技术在铟产业中的应用力度。ITO纳米粉体生产是当前铟深加工的热点，该项目的有效实施，一方面可为整合我省铟资源提供新的思路、为我省铟系列产品开发打下基础，另一方面，可以确保我省以粗铟和高纯铟产品为主导产品的生产厂家在市场竞争上立于不败之地：以原料为依托，以深加工产品为保障，根据市场调整战略目标和生产任务；从而在国际国内市场上保持高的市场竞争力，大幅提高企业抗市场风险的能力。高品质ITO纳米粉体是先进成膜技术、高性能膜、高质量靶材等关键材料，其技术开发及应用，可填补我国在该领域的生产空白。

高质量ITO粉体作为平板显示器必不可少的材料, 其用途广泛, 用量大, 截止到目前尚无有效廉价材料取代。随着新的显示方法的出现, 对ITO的成膜技术, 膜性能等提出了越来越高的要求，比如在液晶显示器中, 随着显示器从TN到STN, 以至于TFT液晶, 对ITO的成膜工艺与成膜质量的要求发生了巨变。新技术、新产品提出的新要求都集中反映在对ITO粉体的质量上。因此，提高ITO粉体品质是必由之路。目前高品质ITO粉体只有西方少数国家能够生产，国内没有生产能力，所需材料全部从国外进口。本项目的实施可填补当前我国在高品质ITO粉体生产的空白。

高品质ITO纳米粉体具有良好的市场和经济价值

作为高品质ITO粉末的下游产品，ITO靶材、玻璃电极及ITO薄膜的需求和产量大幅增加。ITO透明薄膜的需求量以每年35％的速度高速增长，ITO靶材的需求量也大幅上升；同时，我国LCD生产厂家从2002年的20余家急增至目前的100多家，产量急剧增加。在利润方面，以ITO纳米粉体生产靶材计，每吨铟可增值115万美元，其利润丰厚。

建设地的自然条件和社会经济情况：基于云南省具有丰富的铟资源及高纯金属铟的生产优势，本项目通过云南省金属铟生产企业与在纳米材料和功能材料技术研究方面具有良好工作基础的高校合作，进一步对铟资源产品进行深加工开发，系统而深入地开发高品质透明电极材料ITO纳米粉体的生产技术及相关生产工艺，通过高新技术提升传统的有色金属产业，使生产企业提升产品结构并取得良好的经济效益，对云南省地方经济的快速发展，打造云南省“有色金属基地”，发展外向型经济有重要的促进作用，并对我国发展面向未来的信息产业中应用的电子材料都具有重要的意义。

Research, Development and Export of ITO Nanometer Powder, a High-Quality Transparent Electrode Material

Project Owner: Xuanwei Jinsha Industrial and Commercial Co., Ltd.

Project Construction Site: Xuanwei Medium-Small Enterprises Incubator

Industrial Category: Hi-tech

Construction Nature: New construction

Brief Description of the Project: The project is to make high-quality transparent electrode material ITO nanometer powder with the “metal one-step gasification process”. Through analyzing the organization and micro structure of ITO nanometer powder and optimizing the preparation process, it is to research and develop the technology to produce high-quality transparent electrode material ITO nanometer powder, enable the enterprise with the capacity to produce high-quality transparent electrode material ITO nanometer powder, so that the production technology and product quality of high-quality transparent electrode material ITO nanometer powder could reach internationally advanced level. Presently, except being used as an additive to welding materials, high-purity indium is mainly sold to Japan for producing ITO powder. China is a country with abundant indium resources, and the metal indium smelted is as high as 200tons, ranking the first place in the world. As an important downstream processed product of indium, transparent electrode material ITO (Indium Tin Oxide) has excellent conductivity and transparency. Its penetration rate of visible light is as high as 95%, its ultraviolet absorption rate is ≥85%, its infra-red reflection rate is ≥70 %, and its attenuation rate against microwave is ≥85%. Simultaneously, the processing properties of ITO membrane is particularly good. ITO membrane has high hardness and resistance against abrasion and corrosion. Therefore, in recent years, ITO transparent electrode material has been extensively applied in active and passive components of TFT, LCD, electrochromatographic window, photovoltaic components, as well as infra-red radiation and reflection thermal mirror membrane, etc. As an important electronic material for today’s information industry, transparent electrode material ITO is mainly applied in the fields of liquid crystal display, solar energy battery, solid EC components, electromagnetic shielding, radar shielding protection and energy-saving buildings, etc., which are more and more demanding for the properties of transparent conductive membranes. High-performance target made of high-quality ITO powder is one of the key technologies to produce transparent ITO membrane, which decides the quality of ITO membrane. Presently, only a few developed countries, such as Germany, United States and Japan are producing ITO powder. China is still at the R&D stage, without forming an industry yet. Some large glass companies, such as Nanbo and Luobo, have built several ITO glass production lines, and their demands for high-quality ITO powder has been increasing. However, they still rely on importing high-quality ITO powder. On the international, with the sharp increase of the transparent electrode consumption, the consumption of ITO powder has also increased sharply. Therefore, the development of high-quality ITO powder has good industrial prospects at home and abroad.

Basis for Implementation of the Project: Market exploitation and feasibility study.

Brief Introduction to the Project Owner: This project was jointly finished by Xuanwei Jinsha Industrial and Commercial Co., Ltd. and Kunming University of Science and Technology.

Roles and Status of the Project in the Area: Production of high-quality ITO powder may effectively improve the present industrial chain structure of indium resources in Yunnan, reinforce downstream processing of indium products, and improve the ability of the products to resist market fluctuations.

As the main producing area of indium resources in China, Yunnan has preliminarily developed a scaled high-purity indium smelting industry. Manufacturing companies with high-purity indium ingots as the main products, such as Mengzi Mineral Smelting Company and Xuanwei Jinsha Company, have come into being, and the production has been increasing year after year. As a primary product, the price of indium ingots has been subject to the impacts of supply and demand on the market, and fluctuated greatly. After the Asian financial crisis in 1997, indium price dropped significantly, and it was 60USD/kg in 2002. In recent years, as the global indium demands increased significantly, the gap between supply and demand also increased, and the indium price also increased significantly. The price reached 600USD/kg in 2003 and over 1,000USD/kg in 2004. Short-term market acts resulted in great fluctuation of raw material prices, requiring the enterprises to improve the ability to resist market risks. Therefore, based on the present production focusing on primary products of indium, it is an important direction for enterprise development to change the industrial chain structure, extend the downstream processing, and enhance the downstream processing capability. The high-quality ITO nanometer powder project is aimed at improving the simplistic status of indium products in Yunnan, improve the downstream processing capability of indium in Yunnan, and reinforce the efforts to apply hi-tech in the indium industry. ITO nanometer powder production is a hot spot for today’s downstream of indium. To effectively implement the project: On one hand, it may provide new train of thoughts for integrating indium resources in Yunnan, and lay a solid foundation for development of indium product series in Yunnan. On the other hand, it may guarantee that the Yunnan manufacturers focusing on primary indium and high-purity indium products stand in an invincible position in the market competition. Depending on the raw materials, and with downstream processed products as the guarantee, it is to adjust the strategic objectives and production tasks according to the market, so as to maintain high level of competitiveness on the international and domestic markets, and significantly improve the ability of the enterprises to resist market risks. High-quality ITO nanometer powder is a critical material for advanced membrane technology, high-performance membrane and high-quality target materials, etc. The R&D of its technology may fill in the production gap in the field in China.

As an inevitable material for flat displayers, high-quality ITO powder has extensive purposes and large consumption quantity, and it cannot be effectively substituted by cheap materials yet. With the appearance of new display methods, it is more and more demanding for the membrane technology and membrane performances of ITO. For example, in liquid crystal displayer, with the displayers developed from TN to STN, and even TFT, the requirements for ITO membrane process and quality have changed greatly. All the new requirements proposed by new technologies and new products focused on the quality of ITO powder. Therefore, improving ITO powder quality is an evitable road. Presently, only a few western countries can produce high-quality ITO powder, and there is no production capacity in China, all the materials need to be imported. Implementation of the project may fill in the gap of high-quality ITO powder production in China.

High quality ITO nanometer powder has good market and economic values

As downstream products of high-quality ITO powder, the demands and production volumes of ITO target materials, glass electrodes and ITO membrane increased significantly. The demands for ITO transparent film has been increasing by 35% per year, and the demands for ITO target materials have also increased significantly. Simultaneously, Chinese LCD manufacturers have also increased from 20 in 2002 to over 100 today, and the production volume increased significantly. In terms of profits, if ITO nanometer powder is used to produce target materials, each ton of indium may add value by 1.15 million USD, which is very profitable.

Brief Introduction to the Natural Conditions and Socioeconomic Conditions of the Construction Site: Based on the advantageous indium resources and production capacity of high-purity metal indium, this project is to cooperate between a metal indium producing enterprise of Yunnan Province and an university that is well grounded in study of nanometer materials and functional material technologies. It is to further conduct downstream processing and development of indium resources, systematically and intensively develop the production technology and relevant production processes for high-quality transparent electrode material ITO nanometer powder. It is to upgrade the traditional nonferrous metal industry with hi-tech, improve the product structure of the manufacturers, and gain good economic returns. It may give as strong push for speeding up the local economic development of Yunnan Province, building Yunnan as a “nonferrous metal base”, and developing external-oriented economy. It is important for electronic materials to be used in the information industry in future.

Brief Description of Process Technology Plan: (1) It is to skillfully use the electric arc heating technology, improve the evaporation temperature, reinforce the gasification effects of metals and alloys; (2) It is to design the special structure of the evaporation reaction area, and purify the reaction environment; (3) It is to realize the entire process of continuous feeding, continuous reaction and continuous powder making, with short process flow. All these guaranteed the creativity and progressiveness of the project products.
