Grinding And Calcination Of Calcium

Jan 01, 1991 Calcination refers to the heating of inorganic materials to remove volatile components. While the decomposition of calcium carbonate to the oxide is the classic example, the process is now a common and important step in the fabrication of a wide range of oxide ceramics, where it is used to improve the processing characteristics in operations such as grinding, compaction and sintering.
