Bauxite

Bauxite is a massive clinker made of raw bauxite after firing at 1500 C. It has small expansioncoefficient, high refractory and good chemical stability. This strain of high-alumina vanadium clinker isproduced through washing, crushing, screening magnetic separation, hydro magnetic separation,drying and other processes. This product has remarkable economic benefits for improving thequalified rate of castings and reducing the cost of castings. Its density is 3.9-4g/cm3, hardness is 7-8,opaque, brittle, very difficult to melt, insoluble in water, soluble in sulfuric acid and sodium hydroxidesolution. It is mainly used in precision casting, refractory products, bauxite cement, abrasive materials,ceramics industry and etc.
