Baryte

Mineral: Baryte

Natural baryte (barium sulphate, chemical formula BaSO4) can be characterised by:

 

  • High inertness in various media
  • High density and, as a result, low oil absorption
  • Medium Mohs hardness of 3
  • High Refractive Index of 1.64
  • Easy wetting
  • Easy to disperse (also compared to precipitated barium sulphate)

Natural barium sulphate comes without any residual salts when compared to precipitated grades. In addition, natural barytes are easier to disperse than precipitated grades.

Application: 

Baryte will provide UV resistance and weatherability and because of its high density will improve sound deadening.
