Mica has excellent heat tolerance and this has led to their use in various fields. Among the types of mica, we can mention phlogopite mica and muscovite. These two types of mica are mica that are used for industrial insulation.
In this section, we will take a brief look at the differences between muscovite mica and phlogopite mica.
In terms of softness, phlogopite mica is softer than muscovite mica.
The heat tolerance of mica phlogopite is higher than that of muscovite.
Muscovite mica has better electrical insulating power than phlogopite.
Phlogopite mica is less used than muscovite and the reason for less use of phlogopite mica is its brown color.
The most important physical benefits of mica phlogopite are:
Ability to drill, cut and shape easily
Has a reddish-brown, yellow, green color
Cut in the form of thin, hard, flexible and elastic transparent sheets
Has acceptable dielectric properties for electrical insulation
Maximum heat tolerance up to 1000 ° C but in case of heavy use approximately from 800 to 900 ° C
Low heat transfer to prevent energy loss
Phlogopite mica is composed of chemicals, potassium, aluminosilicate, iron and magnesium, which have reddish brown, yellowish brown, green, yellow, red, colorless and brown colors, and this mica is also commonly found in metamorphic rocks. It becomes.
The most important and significant applications of mica phlogopite are:
Asbestos replacement: Used in clutch plates and car brake covers.
In the field of automotive: Production of plastic composite body parts because flowgopite increases the hardness of plastic and provides better dimensional stability.
In the field of electronics: It is used to make strong plates in the face of electricity and heat.
The presence of phlogopite has increased the durability of polyesters, epoxies and nylons.
When mica phlogopite is exposed to light, the reflected light is seen in glossy copper, silver and gold colors, but the overall transparency of this type of mica is estimated to be that of pearl to glass, and of course the amount of this transparency depends on It also has the size of a piece.
This product can be offered, produced and offered with a density of 2.9 to 2.75 and a hardness between 2.5 to 2 Mohs.
Mica phlogopite, with its exceptional benefits and applications, has become very popular in the field of industry.
