Its good fluidity, soluble in water, can dissolve in the molten cryolite-alumina melts. It is the main raw materials of aluminum electrolysis
Appearance: white crystle shape powder or solid
USES: alumina powder hardness big can be used as abrasive, polishing powder, high temperature sintering of alumina, says artificial corundum or artificial stones, we can produce the diamond mechanical bearings or clock. Alumina is used for high-temperature refractory brick, crucible, system, porcelain, artificial stones etc, alumina is also the aluminum smelting materials. Has the strong adsorption force and catalytic activity, can make adsorbent and catalysts. Can be used as precision instrument bearing, and horological diamond, grinding wheel, polishes, fire-proof material and electrical insulators. The gorgeous colour with precious stones. As a decorative Artificial ruby crystal laser material can be obtained
