Details

High-temperature alumina is white powder and made through calcining alumina. There are many kinds of alumina among which a –alumina is stable and used widely. It has high melting point, stable thermal properties, hardness of diamond and low conductivity and cannot be corroded by acid or base. This product is widely used in high alumina refractory materials, ceramic components, automotive spark plugs and polishing products. Customers can choose their ideal products according to products’ chemical composition and physical properties.
