Almatis :: Calcined Aluminas
The majority of calcined aluminas are supplied ground (<63μm) or fine-ground (<45μm). The agglomerates are not fully broken down during the grinding, which is a significant difference from reactive aluminas that are fully ground by a batch grinding process. Calcined aluminas are classified by soda content, particle size and degree of calcination.
