Barite

Barite (CAS 13462-86-7), also known as heavy spar, is a naturally occurring barium sulfate mineral processed for industrial use.

Where is Barite used?

• Oil and gas drilling: primary weighting material in drilling fluids to control wellbore pressure and prevent blowouts
• Rubber and plastics: dense inert filler that increases product weight and improves dimensional stability in automotive parts and sound-dampening panels
• Paints and coatings: extender pigment that improves opacity, reduces cost per unit volume, and enhances corrosion resistance in industrial primers
• Printing inks and paper coatings: achieves smooth, high-brightness surface finish for quality print reproduction
• Its high specific gravity and chemical inertness make it a functional filler and weighting agent.

Good to know: API 13A specification governs most oilfield demand and is the dominant commercial standard for oilfield supply.

Commercial specifications

• Particle size distributions tailored to drilling, coating, or filler applications
• Paint and plastics grades in various micronized forms
