Calcination - Digitalfire

The calcining process is used to remove some or all unwanted volatiles from a material (e.g. H2O, CO 2, SO 2) and/or to convert a material into a more stable, durable or harder state. Varying temperatures are employed to calcine various materials, depending on the decomposition temperature of the volatiles being burned out and the degree of ...
