Definition of calcine in English English dictionary
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
Heated to temperature of dissociation; for example, heat gypsum to the temperature where the water of crystallization is driven off
Reduce to calcium carbonate To purify a substance by subjecting it to high temperatures
to heat a ceramic batch material to a temperature below the melting or fusion point causing loss of moisture reduction, or oxidation
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
by the expulsion of some volatile matter, as when carbonic and acid is expelled from carbonate of calcium in the burning of limestone in order to make lime
A process by which a material is heated to a high temperature without fusing, such as heating unformed ceramic materials in a kiln or heating ores, precipitates, concentrates or residues so that hydrates, carbonate, or other compounds are decomposed and volatile material is released
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 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
is the driving out of water and volatile constituents from a solid by heating In the cement industry calcination is the dissociation, i e the de-acidifying, of calcium carbonate
