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)
