Calcination of glass, silica, quartz and alumina fibre textiles
Calcination is a thermal treatment of a solid chemical compound whereby the compound is raised to a high temperature without melting under restricted supply of ambient oxygen (i.e. gaseous O2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition.
The root of the word calcination refers to its most prominent use, which is to remove carbon from limestone (calcium carbonate) through combustion to yield calcium oxide (quicklime).
