What is the properties and composition of high alumina bricks
high alumina bricks Composition of high alumina bricks High alumina bricks according to resource conditions and product requirements, can be used the following types of raw materials: To water-containing aluminum oxide minerals (diaspore, gibbsite, etc.) As the main composition of the high bauxite; Si line stone minerals (including kyanite, andalusite, silliman stone, etc.); Synthetic raw materials, such as industrial alumina, synthetic mullite, fused corundum and so on. China's high alumina bauxite is rich in resources and excellent in texture. The resulting high alumina vanadium is mainly a mixture of two diamonds (α-Al2O3 · H 2 O) and kaolinite. Properties of high alumina bricks a, refractoriness High alumina brick refractoriness is higher more than clay bricks and semi-silica brick, up to 1750 ~ 1790 ℃, are high refractory materials . b, load softening temperature Because high alumina bricks products in the high Al2O3, less impurities, the formation of fusible glass less
