Muscovite is the most abundant form of mica and is often referred to as “white mica.” It is known for its transparency and excellent dielectric strength, making it widely used in electrical insulators and electronics applications. It also has heat resistance up to 500°C, making it useful in high-temperature environments.
Applications of Muscovite Mica:
- Electrical and thermal insulation
- Capacitors
- Industrial heat shields
- Stove windows
Lepidolite is known for its pinkish-purple color and is primarily used as a source of lithium in industrial applications. Although it is not as common as muscovite or phlogopite, lepidolite is gaining attention due to the rising demand for lithium-based batteries.
Applications of Lepidolite Mica:
- Lithium extraction for batteries
- Specialty ceramics and glass
- Decorative uses
Biotite is a black or dark brown mica mineral often found in granite and metamorphic rocks. It is less commonly used in industrial applications due to its lower insulation properties but is still useful in specific applications requiring higher levels of heat resistance.
Applications of Biotite Mica:
- Geology and petrology studies
- Structural insulators in some specific applications
Phlogopite, also known as “amber mica” or “brown mica,” is similar to muscovite but has a slightly lower dielectric strength. However, it can withstand much higher temperatures, up to 900°C, which makes it ideal for more extreme environments.
Applications of Phlogopite Mica:
- High-temperature insulators
- Foundry and furnace insulation
- Automotive components
- Flame retardant coatings
Green Mica :
Ranges from light to olive green to Dark Green. Color as such has negligiable influence on quality.
Ruby mica is preferred epecially in applications requiring high dielectric strength and low power loss. Green mica is also lighter then Ruby Mica and has excellent cleavage permitting it to be split into the thinnest desired film without risk of cracking.
Uses of Green Mica:
- - Electeical & Thermal insulation
- industrial heat shields
- Stove windows
- Aerospace, Drfense and Neutron Detectors
