Before examining the properties of mica talc, we will explain about mica.
Mica is present in both groups of hydrogen potassium and aluminum mineral silicate. This material is a type of fluosilicate whose structure consists of two plates or layers. Mica are found in three types of igneous, sedimentary and metamorphic rocks.
Of the 28 known species of mica, only 6 are common and available. The six types are: muscovite, light mica, biotite, which is usually black, phlogopite, which is usually brown, paragonite, and macroscopic. Usually the first three types, muscovite, light mica and biotite are more common.
Muscovite is an aluminum fluosilicate mineral. This mineral is flexible and elastic, transparent with glass electricity and has a suitable gap for the production of thin sheets and shells. These gaps allow the mica to be easily divided into thin parallel sheets.
Muscovite, often called "white mica", is the lightest mineral of colored mica. It is usually colorless, light or silver, but is sometimes found in yellow or brown.
Phlogopite is a yellow, green or brownish green element of the mica family of flosilicates. Also known as magnesium mica. Phlogopite is sometimes difficult to distinguish from biotite because of its brown color. Phlogopite is essentially a complex of magnesium, aluminum or iron silicate.
Features of mica talc
• Flexible but non-referential
• Heat resistant and does not melt in a flame
Touching it makes the skin oily
• It is not a heat conductor
• Does not dissolve in water
• Endurance against physical pressure
• Having optical transparency
The interesting thing about mica talc is that whatever is exposed to heat and cold does not lose its light transparency.
• Making cosmetics
• Rubber industry
• Resistant to acids and bases and water and oil
• Prevent broken and cracked glass
