Mica Flakes is mica scrap grounded into sizes ranging from 2 mesh to 20 mesh. This material is prepared mainly by the means of rotary hammer crushing machine in which the mica is literally beaten till such time that the required size is not achieved and the material passes out from graded sieves attached therein. We supply mica flakes to oil well drilling companies, Pearlescent Pigment Manufacturers, Gypsum Board Etc.

We are engaged in large volume production and are capable to enter into long term contract with our customers at most competitive price. We are ACP approved company by alibaba.com and could guarantee supply of a consistent high quality product

Mica Powder is a mineral with a high-quality aspect ratio. It is chemically known as Alumina Silicate. It is fireproof in nature with low heat thermal conductivity and excellent thermal stability.
Mica powder can be used in paint and coating, fireproof insulation to reduce the damage of ultraviolet rays or other light and heat damage to the paint film, promote coating acid and alkali and insulation, and strengthen its durability, freezing resistance corrosion resistance, water resistance, etc. It helps to strengthen the adherence to the layer, improve its intensity, brightness, tenacity, and compaction. As a result, it is conducive to reducing the ventilation, preventing speckle and chaps as well as reducing sediment in the paint. As a prior filler in paint, mica flakes and powder can be used to substitute some expensive raw materials in the paint so as to reduce the production cost.

Grade: High Quality, Dustless
Size: 20 to 40 Mesh

APPLICATIONS:

Reinforced structures provide thermal insulation
Fireproof insulation coating
Sound Absorption
As a protective coating and provided waterproofing.

1. CHEMICAL PROPERTIES OF THE MINERAL MICA
Chemical Composition:
The general formula for mica group minerals is XY Z O (OH, F) :
X: Can be K, Na, Ba, Ca, Cs, (HO), or (NH).
Y: Includes Al, Mg, Fe, Li, Cr, Mn, V, and Zn.
Z: Comprises Si, Al, Fe, Be, and Ti.
The chemical properties of mica minerals vary depending on the specific type of mica. However, all micas are silica (SiO2), aluminum oxide (Al2O3), and potassium oxide (K2O). Some micas may contain other elements, such as iron oxide (Fe2O3) and magnesium oxide (MgO). The following table shows the chemical composition of some common mica minerals:
Mica mineral SiO2 Al2O3 K2O Fe2O3 MgO
Muscovite 45.57 33.1 9.87 0 0
Biotite 47.7 30.9 3 10 3
Phlogopite 47.5 31 3 0 15
Of the 28 known species of mica, six are common rock-forming minerals:
Muscovite: The common light-colored mica.
Biotite: Typically black or nearly black.
Phlogopite: Typically brown.
Paragonite: Macroscopically indistinguishable from muscovite.
Lepidolite: Generally pinkish to lilac; occurs in lithium-bearing pegmatites.
Glauconite: A green species found sporadically in marine sedimentary sequences.
