Calcine, Calcination

The calcining process is used to remove some or all unwanted volatiles from a material (e.g. H 2 O, 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 sintering desired in the product.
