Product Description


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.
