The Mica mineral is an interesting metamorphic rock, formed in layers underneath rock that once used to be under the ocean. It is found in many peaks around the world but in highest abundance in the Himalayan mountain range.

 

Due to its physical properties it is effectively used in the manufacture of many products and used as an intermediary product in many industries.

 

The Mica mineral has a very high melting point and tensile strength. In its raw form, the mineral can adhere temperatures up to 800 ̊ C and tension up to 1750 kgf/cm2. Furthermore, it is a very good insulator of heat and electricity.

 

The mineral is excavated as chunks of blocks, but the blocks are actually hundred of layers of sheets stacked one upon the other. These sheets are picked apart by hand and can be cut into any shape and size depending on the required function. The rock may also be grinded and reduced to a powder. Depending on the physical form, the mineral has different industrial uses. Some of these are mentioned below.

 

Mica Block:

 

  • Insulator for Power Cables
  • Lining of Blast Furnaces, Tanks etc.
  • Plates of Motor Tubes, Transformers, Capacitators etc.
  • Tiles for Space Shuttles

 

Mica Sheets:

 

  • Electrical Components: Gauge Glasses, Thermometers, Radiation Plates
  • Peepholes for Boilers, Stoves etc.
  • Biological Research Devices e.g. scanning probe microscopy

 

Ground Mica:

 

  • Paint Industry: pigment extender, color brightener
  • Cosmetics Industry: glitter, lipsticks, lotion etc.
  • Drilling and Concrete: seals pours, reduces circulation loss
  • Rubber Industry: anti-sticking agent, mold filler
  • Decorative and Luster Coating
