Barium Sulfate

Barium Sulfate

  • Barium Sulfate is an inorganic compound with the chemical formula BaSO₄, appearing as a fine, white, odorless powder that is insoluble in water. Known for its high density, chemical inertness, and excellent opacity, it is widely used as a filler and extender in paints, coatings, plastics, and rubber to enhance durability and surface finish. In specialized applications, it serves as a radiopaque agent in medical imaging and as a weighting material in oil and gas drilling fluids. Its non-toxic nature and resistance to acids and alkalis make it a preferred additive across diverse industrial sectors.

What Is Barium Sulfate?

Barium Sulfate (BaSO₄) is an inorganic compound composed of barium, sulfur, and oxygen. Known for its exceptional whiteness, high specific gravity, and chemical inertness, it functions as both an extender and opacifier in various formulations.
In its precipitated form (BaSO₄ ppt), the material is synthetically produced under controlled conditions to achieve superior purity, fine particle size, and high dispersion uniformity. Unlike natural grades, precipitated barium sulfate offers enhanced brightness and consistency, which are essential for achieving smooth, stable finishes in paints, coatings, and plastics.
Its inert nature ensures compatibility with diverse polymers and resins, allowing manufacturers to enhance opacity, gloss, and surface smoothness without affecting the chemical stability of end products.

Key Benefits & Performance Features

These properties make barium sulfate a versatile performance additive trusted across multiple industries.

What is precipitated barium sulfate (BaSO₄ ppt) used for?

Precipitated barium sulfate is widely used as an opacifier and extender in paints, coatings, plastics, rubber, and paper. Its high brightness, chemical inertness, and smooth dispersion make it ideal for improving product opacity and surface finish

How is precipitated barium sulfate different from natural barium sulfate?

BaSO₄ ppt is synthetically produced, offering higher purity, controlled particle size, and uniform dispersion. Natural barium sulfate may contain impurities and uneven particle distribution, making precipitated barium sulfate the preferred choice for high-performance applications.

Who are the reliable barium sulfate suppliers in India?

Trusted barium sulfate suppliers provide consistent quality, competitive pricing, and technical support. Classic Solvents partners with top manufacturers to ensure a stable supply of high-purity precipitated barium sulfate for industrial needs.

What factors affect barium sulphate price?

The barium sulphate price depends on purity, particle size, grade type, and production method. Higher-grade precipitated barium sulfate generally commands a premium due to its superior brightness, fine dispersion, and enhanced performance characteristics.

Can BaSO₄ ppt be used in high-temperature and chemically resistant applications?

Yes, precipitated barium sulfate exhibits excellent thermal stability and chemical resistance. Its inert nature ensures compatibility with polymers, coatings, and adhesives even under extreme conditions.
