Barium Sulfate

Product Overview

Barium Sulfate (BaSO₄) is a white, crystalline, inorganic compound known for its high density, chemical inertness, and radiopacity. It is widely used in medical imaging, coatings, paints, plastics, and industrial applications. Barium Sulfate is non-toxic, insoluble in water, and stable under normal conditions, making it a versatile additive for enhanced opacity, weight, and chemical resistance.

It is a key ingredient in X-ray contrast agents, filler materials, and specialty coatings, and is valued for its high purity, whiteness, and particle uniformity.

Manufacturing & Quality Control

Barium Sulfate is produced via chemical precipitation or mining from barite ores, followed by washing, grinding, and sieving. Quality control ensures:

• High chemical purity and low heavy metal content

• Uniform particle size and distribution

• High whiteness and brightness for coatings and plastics

Each batch undergoes assay, particle size, and purity testing to guarantee product quality.
