It occurs naturally in its crystalline polymorphic ...

Calcined aluminas are alpha-aluminas that consist primarily of sintered agglomerates of individual alumina crystals. The size of these primary crystals depends upon the degree of calcination and the agglomerate size on the subsequent grinding steps. The majority of calcined aluminas are supplied ground (<63μm) or fine-ground (<45μm).
