►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.
