Application

Descriptions:

• Barium sulphate is non qualitative white or yellowish odorless powder or small crystals.

• Barium sulphate is almost insoluble in water, ethanol and acid, but soluble in hot concentrated sulfuric acid, slightly soluble in boiling Hydrochloric Acid.

• Barium sulphate is stable, it'll reduce to Barium Sulfide when heat with carbon.

• Barium sulphate won't change color when meeting with hydrogen sulfide or toxic gas in the air.

• Barium sulphate is non toxic.

Uses:

• Barium sulphate is used as mud weighting agent in oil drilling and natural gas exploration.

• Barium sulphate is used as filling agent in paints, inks, plastics, rubber and electrical storage tank.

• Barium sulphate is used as surface coating agent for photographic paper, calendered paper and copper plate.

• Barium sulphate is used as sizing agent in textile industry.

• Barium sulphate is used as a glass clarifying agent in glass industry; it can play the role of anti-foaming and increasing gloss.

• Barium sulphate can be used as the raw material to produce other barium salts.

• Barium sulphate can be used medically as X-ray contrast agent of digestive system tract.
