About the Industrial Use of Phlogopite

Jul. 07, 2021

Phlogopite is one of the muscovite minerals, an aluminosilicate containing iron, magnesium and potassium. If there is not too much iron in the composition of Phlogopite, it has an important role as an electrical insulating material.

Phlogopite is characterized by a completely cleaved mica with a yellowish-brown color and golden reflections.  It differs from muscovite in that it can decompose in boiling sulfuric acid while producing a milky white solution, whereas muscovite cannot.Muscovite is the most used in industry, followed by auriferous mica.  It differs from muscovite in that it is relatively light in color.

Phlogopite

Muscovite can be corroded by concentrated sulfuric acid, in which it can decompose to produce a milky white solution. The chemical components that replace potassium are sodium, calcium and barium; the chemical components that replace magnesium are titanium, F iron, manganese and chromium; fluorine replaces OH, while the variants of Phlogopite are manganese mica, titanium mica, chromium mica and fluorine mica. Phlogopite is mainly produced in contact metamorphic zones of ultramafic rocks, such as kimberlite and dolomitic barite.  Impure magnesian limestones can also be formed during regional metamorphism. Apatite differs from dolomite in physical and chemical properties, so it has many special features and is used in many important fields.

The most used in industry is leucite, followed by Phlogopite.  It is widely used in building material industry, fireproof industry, fire extinguishing agent, welding rod, plastic, electric insulation, paper making, asphalt paper, rubber, pearlescent pigment and other chemical industries.

Superfine Mica Powder can be used as functional filler for plastics, coatings, paints, rubber, etc. It can improve their mechanical strength, enhance toughness, adhesion, aging resistance and corrosion resistance. In addition to the extremely high electrical insulation, acid and alkali corrosion resistance, elasticity, toughness and sliding, heat and sound insulation, thermal expansion coefficient and other properties, it also takes the lead in the second surface of the plate with smooth surface, large diameter-thickness ratio, regular shape and strong adhesion. Strong and other characteristics. In industry, it is mainly used for insulation and heat resistance, as well as acid resistance, alkali resistance, pressure resistance and peel resistance, as insulation materials for electrical equipment and electrical equipment; secondly, for the manufacture of steam boilers and smelting furnaces. windows and mechanical parts.
