Tabular Alumina also known as white sintered tabular alumina, white tabular alumina, sintered tabular alumina, tabular aluminum oxide, and tabular corundum are high-purity sintered alpha-alumina spheres (in various sizes).Tabular alumina has been fired at extremely high temperatures(>1900) to reduce porosity to a very low level. This high-temperature process leads the growth of large plate-like, alpha-alumina crystals giving “tabular” alumina its name. Tabular Alumina Balls are carefully selected before packaging for size control, roundness and smooth surface.
