►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.

► 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.
