    Industry grade barium carbonate powder CAS NO513-77-9 using

     

    for optical glass and bricks

     

     

     

    ►Description

     

     

           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.

     

     

    ►Specification

     

     

    Item Specification for Frist Grade
    Purity(BaCO3) ≥99%
    Moisture ≤0.3%
    SO4 ≤0.35%
    Iron(Fe) ≤0.004%
    HCL insoluble Matter ≤0.25%

     

     

     

     

    ►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.

     

     

     

    ►Reactions

     

     

        Barium carbonate reacts with acids such as hydrochloric acid to form soluble

     

    barium salts, such as barium chloride:

     

    BaCO3 + 2 HCl(aq) → BaCl2 + CO2 + H2O

     

    However, the reaction with sulfuric acid is poor, because barium sulfate is highly

     

    insoluble.

     

     

     

    ►Application 

     

     

     

    Barium carbonate was widely used for making optical glass and bricks .
