Barium carbonate (BaCO3), also known as witherite, is a chemical compound used in rat
poison, bricks, ceramic glazes and cement.
The mineral is named after William Withering, who in 1784
recognized it to be chemically distinct from barytes. It occurs in
veins of lead ore at Hexham in Northumberland, Alston in Cumbria,
Anglezarke, near Chorley in Lancashire and a few other localities.
Witherite is readily altered to barium sulfate by the action of
water containing calcium sulfate in solution and crystals are
therefore frequently encrusted with barytes. It is the chief source
of barium salts and is mined in considerable amounts in
Northumberland. It is used for the preparation of rat poison, in
the manufacture of glass and porcelain, and formerly for refining
sugar.It is also used for controlling the chromate to sulfate ratio
in chromium electroplating baths.
