Mica definition

Mica Definition:

Mica is a naturally occurring mineral that is based on a collection of silicate minerals and is composed of varying amounts of potassium (K), iron (Fe), aluminum (Al),  magnesium (Mg), and water (H2O).  It can resist nearly all mediums like chemicals, acids, gasses, alkalies, and oils.

Mica belongs to a very important and rather large group of minerals that are highly suitable for several applications. However, its advanced properties make it highly suitable for use in various places.

Mica Advanced properties:

  • Physical: Mica is translucent, easily split into thin films along with its cleavage, optically flat, colorless in thin sheets,  elastic, and incompressible.
  • Chemical: It is a compound hydrous silicate of aluminum, which also contains iron, magnesium, potassium, sodium fluoride, lithium, and also few traces of numerous other elements. It is constant and entirely static to the action of water, acids (except for hydrofluoric and concentrated sulfur), alkalies, conventional solvents,  bases, and oil. It remains almost unchanged by atmospheric action.
  • Electrical: Mica has the exclusive combination of uniform dielectric steadiness, capacitance stability, enormous dielectric power, high Q factor, lower power loss, high electrical resistance, and low-temperature coefficient. It is highly regarded for its resistance to arc and corona discharge without causing any lasting injury.
  • Thermal: It is highly fireproof,  incombustible, non-flammable, infusible, and also can resist temperatures of up to 1000 degrees Celsius/1832 degrees Fahrenheit.  However, this depends on the type and variety of Mica used. It has excellent thermal stability, and lower heat conductivity, and can be easily exposed to high temperatures without visible effect.
  • Mechanical: Mica is highly tough, has high tensile strength, is elastic, and along with being flexible. It has immense compression power and can be machined, die-punched, or hand-cut.

Application:

  1. It is used in paints as a pigment extender and also helps to brighten the tone of colored pigments.
  2. It is a superior insulator. So in the electrical industry, it is used as thermal insulation, and in electronic equipment as electrical insulators.
  3. Its shiny and glittery appearance makes it ultimate for toothpaste and cosmetics.
  4. It is invariably used for fillers, and extenders along with providing smoother uniformity, improving workability, and preventing cracking.
  5. It can be used as an insulator in home attics, and concrete blocks and also poured into open-top walls.
  6. It can also be added to grease to increase its durability and give it a  better surface.
  7. It can also be used as a soil conditioner particularly in potting soil mixes and in gardening plots.
