FAQs of Biotite Mica:

Q: How is Biotite Mica processed and packaged for industrial use?

A: Biotite Mica is mined and refined to achieve a purity greater than 90%, then milled to desired particle sizes (60-400 mesh). It is packaged in robust HDPE or jumbo bags, available in weights of 25 kg or 50 kg, maintaining optimal moisture levels and product integrity during storage and transport.

Q: What are the primary applications of Biotite Mica in industry?

A: Biotite Mica serves critical roles in welding electrodes, oil well drilling fluids, construction materials, paints, plastics, and rubber compounding. Its heat resistance, moderate hardness, and oil absorption properties lend versatility and reliability to these applications.

Q: When should Biotite Mica be selected over other mica types?

A: Biotite Mica is preferred when high heat resistance (up to 600C), superior chemical durability, and darker coloration are desired. Its specific composition suits demanding industrial contexts where stability and performance under stress are essential.

Q: Where can Biotite Mica be sourced in India?

A: As an exporter, manufacturer, and supplier, Biotite Mica can be sourced directly from qualified producers across India. Vendors offer customized sizing and packaging according to customer requirements, ensuring consistent supply for both domestic and international markets.

Q: What benefits does Biotite Mica offer in the production process?

A: Biotite Mica enhances product thermal stability, improves structural integrity, and contributes to homogeneous dispersion in paints, plastics, and rubber. Its controlled bulk density and particle size allow for efficient blending, minimizing waste and ensuring reliable end results.

Q: How does the chemical composition of Biotite Mica influence its industrial performance?

A: The presence of K2O, MgO, Al2O3, and SiO2, along with iron oxides, gives Biotite Mica excellent mechanical strength and resistance to chemical breakdown. This makes it suitable for environments exposed to heat, moisture, and aggressive chemicals.

Q: What is the recommended shelf life for Biotite Mica and why?

A: Biotite Mica maintains optimal properties for up to 12 months when stored in its original HDPE or jumbo bags. Its low moisture content and stable structure prevent degradation, making it a reliable option for long-term inventory management.
