Supply industry grade high purity Barium Carbonate 99.2%
Barium carbonate (BaCO3), also known as witherite, is a chemical compound used
in rat poison, bricks, ceramic glazes and cement.
Witherite crystallizes in the orthorhombic system. The crystals are invariably
twinned together in groups of three, giving rise to pseudo-hexagonal forms
somewhat resembling bipyramidal crystals of quartz, the faces are usually rough
and striated horizontally. It transforms into an hexagonal phase at 1084 K that
changes into a cubic phase at 1254 K
Witherite
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.

Uses
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.
