Alumina (Metal Grade)
Aluminum oxide is a chemical compound with the chemical formula Al₂O₃that is commonly called alumina. Al₂O₃ is significant in its use to produce aluminum metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.

Alpha Alumina Content
Alpha Alumina (Non-Metallurgical Alumina)
Alpha–Alumina is aluminum metal in its highest oxidative state where no more oxidative reactions are possible and it’s more stable chemically and physically. The strong ionic and covalent chemical bonds between Al3+ and O2− gives the material a high melting point, hardness, and resistance to the attack of strong inorganic acids, such as orthophosphoric or hydrofluoric acid.
Carbon Anodes consisting of calcined petroleum coke and coal tar pitch as a binder are consumed in smelters running with prebake technology that are used as anodes in cells of Primary Aluminum Smelter. We supply any size of Anodes under spot or long-term agreements. Carbon pre-baked anode, electrode paste and recarburizers are core products with lower Ash content, Lower Sulfur content and Higher Compress strength.
