    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.
