Barite

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

Its high specific gravity and chemical inertness make it a preferred functional filler and weighting agent where density and stability are critical procurement criteria for manufacturers.

In oil and gas drilling, it is the primary weighting material added to drilling fluids to control wellbore pressure and prevent blowouts. API-grade specification governs most of this demand.

Rubber and plastics compounders incorporate it as a dense inert filler to increase product weight and improve dimensional stability in automotive parts and sound-dampening panels.

Paints and coatings formulators use it as an extender pigment to improve opacity, reduce cost per unit volume, and enhance corrosion resistance in industrial primers.

Printing inks and paper coatings also rely on it to achieve the smooth, high-brightness surface finish required for quality print reproduction and high-end commercial applications.

The material is supplied as a fine white to off-white powder, with particle size distributions tailored to drilling, coating, or filler applications for various industrial processes.

Material meeting API 13A specifications is the dominant commercial standard for oilfield supply. Paint and plastics grades are available in various micronized forms for specific needs.
