High-purity alumina refers to alumina with a minimum purity of 99.99%. Due to its outstanding characteristics such as porosity, high dispersion, insulation, and heat resistance, it has become a major branch of advanced inorganic non-metallic materials. In recent years, due to the wide range of applications of high-purity alumina, the large range of product serialization and extension, and the high degree of relevance to other high-tech industries, its application market is very broad, and as the application field continues to expand, products are continuously derived Derivation and development, the prospect of the high-purity alumina market is extremely optimistic.
Capacity analysis of the international high-purity alumina market
The global high-purity alumina manufacturers are mainly concentrated in Japan and China. The leading international companies are mainly concentrated in Japan, mainly Sumitomo Chemical, with a total production capacity of approximately 20,000 tons. Among them, Sumitomo Chemical is the company with the largest market share, accounting for 60% of the global high-end market. Japan’s Sumitomo Chemical Co., Ltd. uses the aluminum-alcohol method to produce 3,200 tons at the Ehime plant and 1,600 tons at the Korean plant, for a total of 4,800 tons. The Korean factory is mainly used for the production of heat-resistant separators and electrode layers for lithium batteries.
Orbite Aluminaelnc of Canada can produce high-purity alumina with a purity of 5N-6N through a unique process with a production capacity of 2,000 tons.
South Korea's Dongho (Sumitomo subsidiary) and Japan Light Metal Co., Ltd. have production capacities of 1,600 tons and 1,000 tons, respectively.
The production capacity of other well-known foreign companies RHT, HMR, Sasol and others totals about 10,000 tons.
