Abrasive grade bauxite (Total 3 Products)

Abrasive grade bauxite, the calcined bauxite for abrasive, the most important raw material of BFA(brown fused alumina). Abrasive grade calcined bauxite has an Al2O3 content of 80-88% and a maximum silica content of 5%. The ratio of iron to silica should not exceed 3:1. The titania content, important in controlling the crystal structure and the hardness of the alumina grain, must be in the range of 2-4%. When it comes to calcining, refractory grade bauxite is usually fired at temperatures in the
