Product Description

 

 

Industry grade barium carbonate powder CAS NO513-77-9 using

 

for optical glass and bricks

 

 

 

►Description

 

 

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

 

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

 

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%
Moisture ≤0.3%
SO4 ≤0.35%
Iron(Fe) ≤0.004%
HCL insoluble Matter ≤0.25%

 

 

 

 

►Preparation

 

 

 

        Barium carbonate is made commercially from barium sulfide either by

 

treatment with sodium carbonate at 60 to 70 °C (soda ash method) or by passing

 

carbon dioxide at 40 to 90 °C.In the soda ash process, solid or dissolved sodium

 

carbonate is added to barium sulfide solution, and the barium carbonate precipitate

 

is filtered, washed and dried.

 

 

 

►Reactions

 

 

    Barium carbonate reacts with acids such as hydrochloric acid to form soluble

 

barium salts, such as barium chloride:

 

BaCO3 + 2 HCl(aq) → BaCl2 + CO2 + H2O

 

However, the reaction with sulfuric acid is poor, because barium sulfate is highly

 

insoluble.

 

 

 

►Application 

 

 

 

Barium carbonate was widely used for making optical glass and bricks .
