Baryte

Baryte (also referred to as barite or barytes) is the naturally-occurring form of barium sulphate (BaS04). It has a high specific gravity (4.5) and very low solubility.  

Our natural baryte is used mainly in the following applications: 

– Coatings: to improve UV resistance, sandability, chemical resistance and gloss control, to increase density, and as a cost-effective replacement for precipitated baryte. 

– Polymers: to improve sound proofing in plastics and opacity in resin systems, to increase weight, and as a cost-effective replacement for precipitated baryte.  

– Automotive: to improve friction in brake linings. 

Key characteristics of natural baryte include: 

– high inertness  

– high density, resulting in low oil absorption 

– medium Mohs hardness of 3 

– high refractive index of 1.64 

– easy wetting 

– easy dispersion
