Superior Filler for Multiple Industries

Precipitated Barium Sulphate serves as a premium filler, pigment, and extender in industries such as paint, plastics, rubber, inks, paper, and glass. Its high level of whiteness, fine particle size, and excellent mechanical strength ensure optimal performance in end applications, improving durability and surface finish while maintaining chemical inertness and stability.

Strict Quality and Performance Guidelines

Formulated to achieve a consistent and reliable result, this barium sulphate features <0.05% chloride, <50 ppm iron content, and a pH between 6.5 and 8.5 in slurry form. Its production process ensures a smooth, fine powder with extremely low porosity, negligible water absorption, and high strength, making it suitable for even the most demanding industrial uses.

Safe Storage & Long Shelf Life

This product remains stable for up to 24 months from the manufacturing date when stored in a cool, dry place within tightly closed containers. The low moisture content (max 0.2%) and good chemical stability maintain product quality and usability over its shelf life, ensuring consistent and safe performance in your operations.

FAQs of Barium Sulphate Precipitated:

Q: How should precipitated barium sulphate be stored to maintain optimal quality?

A: Precipitated barium sulphate should be stored in a dry environment with the container tightly closed. This helps prevent moisture uptake and contamination, ensuring the product maintains its desired properties and effectiveness for up to 24 months.

Q: What are the main benefits of using barium sulphate as a filler in manufacturing processes?

A: Barium sulphate provides high mechanical strength, superior whiteness, smooth surface finish, and very low thermal conductivity. Its neutral refractory nature and inertness enhance product durability and performance in applications like paints, plastics, and glass.

Q: Where is precipitated barium sulphate typically applied within industry?

A: This product is widely used as a filler, pigment, and extender in paints, plastics, rubber, inks, paper, and glass manufacturing. Its properties allow for improved physical characteristics and stability in the end products.

Q: What process is used to achieve the high purity and fine particle size of this barium sulphate?

A: Precipitated barium sulphate is synthesized through a controlled chemical precipitation method, resulting in a fine powder with a consistent particle size (15 microns) and high purity (9899.5% BaSO4), making it suitable for sensitive industrial applications.

Q: When does barium sulphate reach the end of its shelf life?

A: Stored under recommended dry and sealed conditions, precipitated barium sulphate retains its properties for up to 24 months from the manufacturing date, after which it should be evaluated before use to ensure quality.

Q: What are the specific physical characteristics that make this product suitable as a filler?

A: Its fine powder form, high specific gravity (4.34.5), smooth surface finish, and negligible porosity and water absorption make it an exceptional filler that improves texture, opacity, and strength of composite materials.
