About this product

Product information from the supplier.

Biotite Mica is a premium-grade dark mica mineral renowned for its exceptional physical and chemical stability. Characterized by its unique layered structure and vitreous luster, this versatile mineral is essential for high-performance industrial applications. With a Mohs hardness of 2.5 to 3, it allows for precise cleavage into thin, flexible sheets, making it an indispensable raw material in the manufacturing of specialty coatings, high-end paper, and advanced drilling fluids.

Our Biotite Mica is engineered to meet the rigorous demands of modern industry, offering superior heat stability, low thermal conductivity, and excellent chemical resistance. Whether utilized as a functional filler in plastics and rubber or as a critical additive in oil drilling muds to enhance viscosity, our product ensures maximum efficiency and durability. Furthermore, its antibacterial and deodorizing properties make it a breakthrough material for the production of high-quality non-woven fabrics used in medical-grade face masks.

Frequently Asked Questions

Q: What makes Biotite Mica suitable for oil drilling?

Biotite Mica acts as a high-efficiency thickening agent in drilling muds, improving viscosity and stability. Its resistance to corrosion and high temperatures ensures the drill bit is cooled and rock cuttings are carried to the surface safely.

Q: How does Biotite Mica improve paper quality?

When incorporated into pulp, it enhances structural integrity, durability, and wear resistance. Additionally, its natural luster provides a smooth, glossy finish ideal for luxury packaging and artistic papers.

Q: Can Biotite Mica be used in medical masks?

Yes, it is highly popular in non-woven fabrics for masks. It is first made into a masterbatch, then combined with antibacterial materials to provide deodorizing and far-infrared ray functions.

Q: What are the common mesh sizes available?

We offer a wide range of specifications, including 4-6, 10-20, 40-60, 325, 600, 1000, and up to 3000 mesh to suit various industrial needs.

Q: Is your Biotite Mica certified?

Our factories are ISO certified, and we hold 23 national patents for our production technologies, ensuring a high-quality and consistent supply.

Q: What other industries use this mineral?
