to heat something without melting in order to drive off water etc., and to decompose carbonates into oxides or to oxidize or reduce it; especially to heat limestone to form quicklime
To reduce to a powder, or to a friable state, by the action of heat; to expel volatile matter from by means of heat, as carbonic acid from limestone, and thus (usually) to produce disintegration; as to, calcine bones
Describes the high temperature treatment of catalyst precursor materials, converting them to strong, stable solids The term comes from ceramics technology, where calcining or firing is used to convert clay intermediates (green materials) to finished products
