Analysis on the application market and production status of high-purity alumina
China Powder Network News High-purity alumina powder has high purity (Al2O3≥99.99%), fine and uniform particle size, and has light, thermal, magnetic, and electrical characteristics that are superior to conventional materials. One of a wide range of high-end materials. At present, the annual global demand for high-purity alumina exceeds 7500t, and the main production areas are concentrated in Europe and the United States. China's alumina production is mainly industrial alumina, and product purity and particle size are difficult to meet the high-end market demand. With the development of China's economy, the demand for high-purity ultra-fine alumina powder will continue to increase. 1. Application and market demand of high-purity alumina High-purity alumina has outstanding characteristics such as porosity, high dispersion, insulation, and heat resistance. It is used in artificial crystals, fine ceramics, transparent ceramics, bioceramics, and semiconductor integrated circuits. The substrate and other aspects have been widely used. Generally 3N high purity alumina is mainly used for advanced ceramics, 4N high purity alumina is mainly used for phosphors, 5N high purity alumina is used for sapphire crystals, lithium battery separators, advanced ceramics, PDP phosphors and ...
