Product Description
Abrasive grade bauxite, the feedstock for brown fused alumina, is prepared from low silic, low alkali material that is alcined at
temperatures of approximately 1100 C. The minimum alumina content of 80% on a calcined basis is normally required for this
application. And the upper limit on the silica content is 5%. Titania is ideally in the range of 2% to 4%. And low concentrations of
alkalies are a requisite in order to minimize the formation of a glass phase. Besides these strict chemical specifications, particle
size is especially critical for abrasive production. The upper limit on particle size is 50mm with the lower threshold set at a 100
mesh screen size.
Application of our abrasive grade calcined bauxite:
Some calcined bauxite is used directly as an inexpensive abrasive product, but by far the largest amount is used as the feedstock
for the manufacture of brown used alumina. Brown fused alumina is produced by the electrofusion of calcined bauxite in electric
arc furnaces at temperatures in excess of 2000 ºC
