Frequently Asked Questions
Q: What makes Phlogopite Mica superior to Muscovite for refractories?
Phlogopite has a significantly higher resistance to heat and thermal stability, allowing it to maintain strength and form in extreme temperatures where muscovite would degrade.
Q: What are the primary differences between dry ground and wet ground mica powder?
Dry grinding preserves natural properties through physical grinding, while wet grinding involves purification and washing to achieve higher purity, glossiness, and a better radius-thickness ratio.
Q: In which industries is Phlogopite Mica Paper typically used?
It is widely used in the automotive, electronics, and energy sectors for creating heat-resistant gaskets, seals, and electrical insulation components.
Q: Can the particle size of the mica powder be customized?
Yes, we offer a comprehensive range of specifications from coarse 4-6 mesh to ultra-fine 3000 mesh to meet precise industrial requirements.
Q: What is the chemical advantage of Biotite Phlogopite?
Biotite phlogopite contains additional iron, which enhances its mechanical strength and flexibility, making it ideal for components subjected to physical stress at high temperatures.
Q: How is the quality of the mica powder guaranteed during production?
We utilize a totally enclosed filling system and proprietary screening technology, backed by ISO certification and national patents to ensure stability and purity.
