    ►Description

          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

     

    baths.

     

     

    ►Specification

     

     

    Item Specification for Frist Grade
    Purity(BaCO3) ≥99%

    ► 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

     

     

     

     

    ►Application 

     

     

          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. 

     

     

    ►Toxicity

     

           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.
