What is Natural Barium Sulfate?
Natural Barium Sulfate is a white crystalline powder derived from high-purity barite (BaSO₄), mined and ground into ultra-fine particles without any chemical modification. It is widely used as a functional filler and extender due to its chemical stability, non-toxicity, and high density.
With its natural origin, Natural Barium Sulfate offers a cost-effective alternative to precipitated grades, while still maintaining key performance parameters for a wide variety of applications.
Key Benefits of Natural Barium Sulfate
✅ High Specific Gravity (4.2 – 4.4 g/cm³) – Excellent for weight-sensitive or radiation shielding applications.
✅ Superior Chemical Inertness – Stable in acidic, basic, and high-temperature environments.
✅ Cost-Effective Filler – Reduces resin or pigment usage in plastics, paints, and rubber.
✅ Bright White Appearance – Enhances color, opacity, and UV resistance in coatings and films.
✅ Non-Toxic & Environmentally Safe – 100% mineral-based, meets global safety and compliance standards.
