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 :

 

 

      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

 

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.

►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.

 

►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.
