Brown Fused Alumina is fused in an electrical furnace by high temperature.its main raw materials
are bauxite.anthracite.it dispaly brown.its chemical composition contains Al2O3,a small amount of
SiO2.TiO2.and Fe2O3.etc.the microhardness is 1800-2200kg/mm2.
the toughness is higher than silicon carbide.abrasive articles made of it are suited for grinding
metals of highten sile strength such as steel.annealed malleableiron and hard high-class
refractory products.the degree of refractory is up to 1850 centgrade.
