    Detailed Product Description
    Density: 4.43 EINECS: 208-167-3
    Molecular Weight: 197.34 Appearance: White Powder
    Purity: 99% CAS NO: 513-77-9


    BaCO3 CAS NO 513-77-9 one the main uses of barium carbonate is produce ceramic capacitors


          Barium carbonate is a white fine powder.


         Barium carbonate (BaCO3), also known as witherite, is a chemical compound


    used in rat poison, bricks, ceramic glazes and cement.


         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.



    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

    ► Production method 



    (1) Carbonation method: carbon dioxide is passed through barium sulfide


    solution  to carbonize, the obtained barium carbonate slurry is desulfurization


    washed, vacuum filtration, dried at 300℃ and pulverized to obtain barium


    carbonate products. its

    BaS + CO2 + H2O→ BaCO3↓+ H2S↑

    Metathesis method: barium sulfide and ammonium carbonate proceeds metathesis


    reaction, and then washing, filtering and drying to obtain bismuth products. its


    BaS + (NH4) 2CO3 → BaCO3 ↓ + (NH4) 2S


    (2) Carbonization method.


    Reaction equation:

    BaS + CO2 → BaCO3 ↓ + H2S ↑


    Metathesis method. Reaction equation:

    BaCl2 + NH4HCO3 + NH4OH → BaCO3 ↓ + 2NH4Cl + H2O

    Reaction equation:

    BaCO3 + 2NH4Cl → BaCl2 + 2NH3 + H2O + CO2

    BaCL2 + (NH4) 2CO3 → BaCO3 ↓ + 2NH4Cl








          Barium carbonate is widely used in high-voltage AC capacitors, ultrasonic


    transducer devices and piezoelectric ceramic capacitor manufacturing.

    The piezoelectric effect was first discovered on quartz crystal by the Curie brothers


    in 1880, the crystal which can produce the piezoelectric effect was called


    piezoelectric crystal. 





           This product is toxic virulent. Chronic poisoning mainly accumulates in the


    bone, causing bone marrow leukosis. Severe acute poisoning can cause acute


    gastrointestinal disorders, tendon reflexes, convulsions, muscle paralysis.


    Emergency treatments include gastric lavage, enema, taking measures like


    vomiting. Maximum allowable concentration is 0.5 mg/m3. Production should wear


    overalls, masks, gloves.
