►Preparation
Barium carbonate is made commercially from barium sulfide either by
treatment with sodium carbonate at 60 to 70 °C (soda ash method) or by passing
carbon dioxide at 40 to 90 °C.In the soda ash process, solid or dissolved sodium
carbonate is added to barium sulfide solution, and the barium carbonate precipitate
is filtered, washed and dried.
►Application
Barium carbonate is widely used in the ceramics industry as an ingredient in
glazes.
It acts as a flux, a matting and crystallizing agent and combines with certain
colouring oxides to produce unique colours not easily attainable by other means.
Its use is somewhat controversial since some claim that it can leach from glazes
into food and drink.
To provide a safe means of use, BaO is often used in fritted form.
In the brick, tile, earthenware and pottery industries barium carbonate is added to
clays to precipitate soluble salts (calcium sulfate and magnesium sulfate) that
cause efflorescence.
