china barium sulfate
Product Features：
The refractive index of this product is 1.64, same as most of the synthetic resin.and the particle size is nano grade, good transmittance of visible light during390-780 nm, the optical property is very good.
With special surface coated technology, low oil absorption, good distribution,good affinity with many kinds of resin, make the final product good mechanicalproperty, improve the filling rate, reduce the final cost.
High L value, could guarantee the final product high glossy and good brightness.
Without halogen, could guarantee the final product safety and cleanliness.
China Barium Sulfate
China is one of the world’s leading producers and exporters of barium sulfate, offering both natural baryte-based and synthetic precipitated grades. Chinese barium sulfate is widely recognized for its high purity, consistent quality, and competitive pricing, making it a trusted choice across global markets.
Product Overview:
Barium sulfate (BaSO₄) is a white, odorless, and chemically stable powder with exceptional brightness and high specific gravity. It is used as a functional filler, extender, or weighting agent in various industrial applications.
Key Advantages of China-Sourced Barium Sulfate:
Wide Range of Grades: From standard natural barite to high-purity synthetic types
Stable Supply & Large Reserves: Rich barite resources across provinces like Guizhou, Guangxi, and Sichuan
Cost-Effective: Efficient production and logistics enable globally competitive pricing
Customization Available: Particle size, surface treatment, and purity levels tailored to customer needs
Compliance with Global Standards: REACH, ISO, and other certifications offered by leading manufacturers
Main Applications:
Paints & Coatings: Enhances whiteness, gloss, and UV resistance
Plastics & Polymers: Improves rigidity, dimensional stability, and surface finish
Oil & Gas: Used as a weighting agent in drilling muds
Printing Inks: Boosts opacity and color performance
Medical Use (synthetic, pharma-grade): As a contrast agent in radiology (X-ray imaging)
Synthesis Process：
Produce the nano barium sulfate with carbonate solution and sulfuric acid andcoated with special technology.
