About Mica

Mica is a group of silicates having a prismatic angle 120, eminently perfect basal cleavage, affording than tough laminae or scales, colorless to jet black, transparent to translucent, of widely varying chemical composition and crystallizing in the monoclinic system.

Mica is formed by flat six-sided monoclinic crystals with a remarkable cleavage in the direction of the large surfaces, which permits them to split easily into optically flat films, as thin as one micron in thickness. When split into thin films, they remain tough and elastic even at high temperature.

The crystal structure of MICA is silicon as basic skeletal structure. Its stratified combination is connected by potassium atoms and is separated by cut off combination at this place due to the binding force of potassium and oxygen is very weak.

The chemical composition of mica varies significantly with mining areas. The most important micas for industrial use are Muscovite mica that consists of potassium as a key ingredient and Phlogopite mica that consists of magnesium.

Mica is used in the electrical industry as a dielectric in capacitors and as an electrical insulator in motors, electron tubes, transistors, and appliances such as toasters, kettle, oven and flatirons.

Ruling governing hygiene and safety forbid the use of asbestos, which fibrous nature constitutes a health hazard.

All Mica Products are 100% ASBESTOS FREE processed from Natural Mica that are totally harmless. They represent very high thermal and mechanical performances, leading it to successfully replace asbestos in most of application in total.
