Barium Sulfate Applications

Barite (barium sulfate) is used in a variety of industries and applications, including paints and coatings, plastics and rubber, building and construction; sound deadening and friction.

  • Paint and coatings
  • Polymers
  • Friction Materials
  • Polyester Molding and Joint Compound
  • Foams

What Is Barium Sulfate?

Barium sulfate is a rather unique mineral having several key attributes that make it a valuable functional filler. These characteristics include:

  • Ability to be bright white and having high refractive index (1.65) for TiO2 Extension
  • Very Dense with a specific gravity as high as 4.4
  • Chemically inert – highly resistant to acids and base
  • Thermally stable with a melting point of 1580 C
  • Low abrasivity: 2.5 – 3.5 on Moh’s scale
  • Low oil absorption relative to particle size (one micron with oil absorption of ~ 15)
