Industry grade 99% white witherite powder mainly used for ceramics and optical glass
►Description
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 :
1. Witherite (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
electrolysis
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.

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.
►Application
Witherite (Barium carbonate) was mainly used for ceramic glaze and optical glass
►Warning
Harmful if swallowed.
Use personal protective equipment.
Ensure adequate ventilation.
Wash off immediately with plenty of water for at least 15 minutes.
Get medical attention immediately if symptoms occur.
Rinse immediately with plenty of water, also under the eyelids, for at least 15
minutes. Obtain medical attention.
Move to fresh air. If breathing is difficult, give oxygen.
Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the
substance; induce artifici.
Get medical attention immediately if symptoms occur.
Do not induce vomiting.
