Product Description

Industry grade 99% white witherite powder mainly used for ceramics and optical glass



   Witherite (Barium carbonate) is a white powder. 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.



There have three  different powder as below :



      1Witherite (Barium carbonate) standard powder is used in the production of


special glass, glazes, brick and tile industry, ceramic and ferrite industry, also used


for removing of sulfates in phosphoric acid production and chlorine alkali




      2. Witherite (Barium carbonate) fine powder is specially developed for usage in


the brick and tile industry and for the removing of sulfates.Other applications are in


the ceramic and ferrite industry. It is also used in the production of chlorine alkali


electrolysis and for the purification of phosphoric and tartaric acid.


      3. Witherite (Barium carbonate) granular is used for the production of display


glass, crystal glass and other special glass, glazes, frits and enamels, also used in


the chemical industry.

►Methods of manufacturing


      Witherite (Barium carbonate) is made from barium sulfide soln by one of two methods.


In the first, the soda ash method, the barium sulfide soln is treated with sodium


carbonate, either dissolved or in solid form, producing barium carbonate and


sodium disulfide.The usual operating temp is 60-70 deg C. The resulting slurry is


filtered and the barium carbonate is washed, dried, ground, and packaged. This


process is thought to be used by about half of the industry .


In the second main method, carbon dioxide gas is passed through a barium sulfide


soln, either batchwise or on a continuous basis, at 40-90 deg C. Temp and other


operating conditions have a pronounced effect on the size and characteristics of the


particles formed. To obtain a satisfactory product, the barium sulfide must react with


slightly less than the stoichiometric amt of carbon dioxide; the carbon dioxide may


be supplied in pure form, or may be obtained from the combustion gases of barium


sulfide reduction kilns.




Witherite (Barium carbonate) was mainly used for ceramic glaze and optical glass
