Barium Sulfate Production Process

Barium sulfate - Wikipedia

Almost all of the barium consumed commercially is obtained from barite, which is often highly impure. Barite is processed by carbothermal reduction (heating with coke) to give barium sulfide: BaSO4 + 4 C → BaS + 4 COIn contrast to barium sulfate, barium sulfide is soluble in water and readily converted to the oxide, carbonate, and halides. To produce highly pure barium sulfate, the sulfide or chloride is treated

The production and uses of Barium sulfate katezhou

2011-09-10  About 80% of the world’s barium sulfate production, mostly purified mineral, is consumed as a component of oil well drilling fluid. It increases the density of the fluid. The majority of synthetic barium sulfate is used as a component of white pigment for paints. In oil paint, barium sulfate is almost transparent,and is used as a filler or to modify consistency. Besides, barium sulfate

Barium Sulfate - an overview ScienceDirect Topics

Barium sulfate is extracted from mined barites, and undergoes grinding and classification to yield particles sizes suitable for use in coatings. As mentioned previously, barium sulfate has a higher specific gravity ( ρ = 4.5 g cm −3 ), and hence leads to higher specific gravity coatings, or lower coverage coatings (i.e., the coating covers a lower area for a given weight).
