Mica

Mica refers to a transparent clear mineral that has high levels of dielectric strength. Mica can endure a continuous temperature of about 550°C; its melting point is estimated to be 1250°C. Mica has the capacity to endure all agents including acids, chemicals, oils, gasses and alkalis. The mineral derives its name for a Latin term, micare, which implies its glittery appearance. Mica is one of the minerals that retain a glimmer and shine when exposed to a direct source of light. Mica belongs to the silicate class of minerals but it also exhibits monoclinic features similar to those exhibited by crystals. It also belongs to other crucial bigger groups of minerals and is appropriate for various applications. For instance, Muscovite mica, which has transparent material, is appropriate for optical use such as development of protection shields, sight glasses, window plates and protection discs. Phlogopite mica has a greyish brown color and is suitable for electrical protection.

Mica Applications

Mica occurs naturally in minerals that contain silica. It is commonly used in gypsum wallboards where it prevents cracks and acts as padding. Mica is also used as a pigment extension in paints. It is useful for brightening colored pigment’s tone. Within the electrical sector, it is useful in developing thermal and electrical insulators used in electronic equipment. Due to its glittery and shiny look, mica is largely used in cosmetics and toothpaste. Its high levels of thermal resistance make it an ideal insulator in electronics. Mica contains high levels of silica which make it a preferred mineral in different industries. It is used as filler and extender as well as an agent for enhancing uniformity and improving functionality. It is poured in top wall openings and concrete blocks and is also added to grease to increase its durability and surface smoothness. It is also used to condition soil especially in gardening areas.
