A process in which a material is heated to a high temperature without fusing, so that hydrates, carbonates, or other compounds are decomposed and the volatile material is expelled.

(n) the conversion of metals into their oxides as a result of heating to a high temperature

formation of a calx, i.e., oxidation of a metal, often by roasting. [Bacon, Black; Lavoisier 1, 2, & 3; Rey] calomel: mercury(I) chloride, Hg2Cl2.

the process of roasting metallic concentrates to remove sulphur prior to smelting.

The heating of a solid to a high temperature, below its melting point, to yield the degree of sintering and agglomeration of diatomite particles needed to result in a particular flow rate permeability. Calcining can be effected over a range of temperatures up to about 1300° C.

A thermal treatment process applied to ores and other solid materials in order to bring about a thermal decomposition, phase transition, or removal of a volatile fraction. The calcination process normally takes place at temperatures below the melting point of the product materials. Calcination is to be distinguished from roasting, in which more com [..]

Calcination is heating material to release volatile constituents or change the crystal structure. Calcined Products - Oxides : Quicklime, dolime

Calcination is the heating of a substance so that a physical, or chemical change occurs. In the case of limestone, it refers to the dissociation of calcium and magnesium carbonates into calcium and magnesium oxide with evolution of carbon dioxide gas.
