Frequently Asked Questions (FAQs)
1. What are the main differences between Phlogopite and Muscovite mica?
Phlogopite mica is typically brown or greenish and can withstand higher temperatures compared to muscovite mica, which is usually clear or silvery. Phlogopite is preferred for high-temperature applications, while muscovite is more commonly used for electrical insulation.
2. Can phlogopite mica be used in food-grade applications?
No, phlogopite mica is not typically used in food-grade applications due to its chemical composition and potential impurities. For food-grade applications, muscovite mica is usually preferred.
3. What is the shelf life of phlogopite mica products?
Phlogopite mica products have an indefinite shelf life as long as they are stored in dry and stable conditions. Proper storage will prevent moisture absorption and maintain the material’s properties.
