The word Mica is derived from the Latin word “micare”, which means “to shine”, in reference to its glittering effect when exposed to light. Mica is a non-metallic mineral that exhibits perfect basal cleavage. The mica group represents a total of 37 different types of mica. Muscovite and Phlogopite are important micas for commercial application. Muscovite is by far the most frequently mined and used type of mica. A typical chemical composition of Muscovite Mica is silica (SiO2) – 45%; alumina (Al2O3) – 38%; potassium oxide (K2O) – 12%; other – 5%

- Varied properties – Multiple uses
Mica’s reflective optical properties are utilized in cosmetics as well as in paints & coatings. Besides it’s glittering and aesthetic effects, mica is used in a wide range of industrial applications. The construction and plastic industries use mica as a functional filler. Given its diverse properties and applications, mica is found in a significant number of parts and materials used in the automotive industry. Mica can withstand high temperature which makes it a useful component for welding and frictional systems. Mica is used as a lubricant in the oil & gas drilling sector.

- Some important characteristics of Mica
- Chemically inert, i.e. it does not react to water, acids, oil or solvents.
- Lightweight, flexible and strong.
- Resists extremely high temperatures and sudden changes in temperature.
- Withstands high voltages and insulates with low power loss.
- Absorbs and reflects light, which enables a decorative effect and protects against ultra-violet (UV) light.

Characteristics
|
| Muscovite |
KAl2(AlSi3)O10(OH)2 |
Rude ore is a brownish natural platy mineral. Octahedral ions in a crystal are mostly occupied with Al. |
| Phlogopite |
KMg3(AlSi3)O10(OH)2 |
Phologopite is darker than muscovite and soft. Octahedral ions in a crystal is mostly occupied with Mg. |
| Sericite |
KAl2(AlSi3)O10(OH)2 |
Rude ore is a greenish gray, natural platy mineral, same composition as muscovite but its smaller crystals due to hydrometamorphism. |
| Synthetic Fluoro Phlogopite |
KMg3(AlSi3)O10F2 |
Synthetic fluorophlogopite, contains no (OH) of the natural phlogopite instead the (OH)- is fully substituted with F. White and a little rigid.
