Chemical alumina refers to aluminum hydroxides, alumina and alumina-bearing compounds apart from alumina used for producing aluminum. The products are widely applied in industries covering artificial panels, pottery and porcelain, fire-resistant materials, laundry, petrifaction, fluoride salt (aluminum fluoride, cryolite), activated alumina, high-temperature alumina, water clarifying agent (polyaluminum chloride and aluminum sulfate), sodium aluminate, aluminum gel raw material for medical use, catalyst carrier, rubber, plastics, fire-resistant packing and glass products. Chalco Shandong Co., Ltd, Chalco Zhongzhou Aluminum Co., Ltd and Zhengzhou Research Institute have an annual capacity of 1.05 million tons, making Chalco the world’s largest chemical alumina producer and supplier.
