    Detailed Product Description
    Description: Witherite CAS NO: 513-77-9
    Density: 4.43 Color: White
    Melting Point: 811 °C Boiling Point: 1450 °C

    Industry grade 99% white witherite powder mainly used for ceramics and optical glass

    ►Description

     

       Witherite (Barium carbonate) is 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.

     

     

    There have three  different powder as below :

     

     

          1Witherite (Barium carbonate) standard powder is used in the production of

     

    special glass, glazes, brick and tile industry, ceramic and ferrite industry, also used

     

    for removing of sulfates in phosphoric acid production and chlorine alkali

     

    electrolysis

     

          2. Witherite (Barium carbonate) fine powder is specially developed for usage in

     

    the brick and tile industry and for the removing of sulfates.Other applications are in

     

    the ceramic and ferrite industry. It is also used in the production of chlorine alkali

     

    electrolysis and for the purification of phosphoric and tartaric acid.

     

          3. Witherite (Barium carbonate) granular is used for the production of display

     

    glass, crystal glass and other special glass, glazes, frits and enamels, also used in

     

    the chemical industry.

     

     

     

    ►Specification

     

     

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

     

     

     

     

    ►Methods of manufacturing

     

          Witherite (Barium carbonate) is made from barium sulfide soln by one of two methods.

     

    In the first, the soda ash method, the barium sulfide soln is treated with sodium

     

    carbonate, either dissolved or in solid form, producing barium carbonate and

     

    sodium disulfide.The usual operating temp is 60-70 deg C. The resulting slurry is

     

    filtered and the barium carbonate is washed, dried, ground, and packaged. This

     

    process is thought to be used by about half of the industry .

     

    In the second main method, carbon dioxide gas is passed through a barium sulfide

     

    soln, either batchwise or on a continuous basis, at 40-90 deg C. Temp and other

     

    operating conditions have a pronounced effect on the size and characteristics of the

     

    particles formed. To obtain a satisfactory product, the barium sulfide must react with

     

    slightly less than the stoichiometric amt of carbon dioxide; the carbon dioxide may

     

    be supplied in pure form, or may be obtained from the combustion gases of barium

     

    sulfide reduction kilns.

     

    ►Application 

     

    Witherite (Barium carbonate) was mainly used for ceramic glaze and optical glass

     

    ►Warning 

     

     

     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.
