Barium carbonate is widely used in the ceramics
industry as an ingredient in glazes
►Description
Barium carbonateis a white powder. Barium carbonate is insoluble in water and
soluble in most acids, with the exception of sulfuric acid. Barium carbonate has a
specific gravity of 4.275. Barium carbonate is toxic by ingestion.
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
Other application
Barium carbonate 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.
Harmful if swallowed.
Use personal protective equipment.
Ensure adequate ventilation.
Wash off immediately with plenty of water for at least 15 minutes.
Get medical attention immediately if symptoms occur.
Rinse immediately with plenty of water, also under the eyelids, for at least 15
minutes. Obtain medical attention.
Move to fresh air. If breathing is difficult, give oxygen.
Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the
substance; induce artifici.
Get medical attention immediately if symptoms occur.
Do not induce vomiting.
Call a physician or Poison Control Center immediately.
