  1.Appearance : 

  White oblique side crystallization or white amorphous powder. 

  2.Other Features:

  Wite color,tasteless, nontoxic. Soluble in hot concentrated sulfuric acid, do not dissolve in water, 

  ethanol and acid. When dry caking. Industrial precipitation of barium sulfate itself not toxic, but if 

  the content of soluble compounds of barium can lead poisoning.

  3.Use: 

  1. As a weighting agent for drilling fluids in oil and gas exploration.

  2. Used in the car, electronics, TV screen, rubber, and glass ceramics and paint industry. 
  3. As surface smear for photographic paper and calendered paper; as sizing agent for textile industry. 
  4. As clarifying agent for glass products. 
  5. Radiation shielding and medical applications etc
