Phlogopite

Muscovite mica is a class of minerals, it is iron, magnesium and potassium aluminum silicate A. Phlogopite composition of iron if not more so, it can be used as electrical insulation materials, and thus plays an important role.

Chemical composition of phlogopite: KMg 3 [Si 3 AlO 10] (OH, F) 2, instead of extensive isomorphism, so the output of different rock in the black mica, a great gap between their chemical composition.

There are synthetic phlogopite phlogopite mica (synthetic mica) and natural mica, natural mica with dark and light mica phlogopite.

As having the characteristics of phlogopite mica complete cleavage, similar to yellow brown color and golden reflections. The difference is that with the muscovite can be decomposed in boiling sulfuric acid, while producing - kind of solution for the emulsion, and muscovite can not; the most used in industry is muscovite, followed by phlogopite. With biotite difference is that color in light. Phlogopite mainly in the ultra-basic rocks such as kimberlite, and dolomitic marble of the contact metamorphic zone. Impure magnesian limestone subjected to regional metamorphism, but also can be formed.

Phlogopite and muscovite because of different physical and chemical properties, so there are many special features, used in many important areas. Major industrial use of its high electrical insulation and heat resistance, and strong acid, alkali, compression, and stripping sub performance, electrical equipment and electrical equipment for the insulating material; followed for the manufacture of steam boilers, smelting furnace furnace and windows and mechanical parts. Phlogopite generally yellow, dark brown or black, glass luster, cleavage appear before or semi-gloss metallic pearl, gold mica, which can be concentrated sulfuric acid corrosion in concentrated sulfuric acid decomposition, while producing a milky solution, chemical alternative ingredients are sodium potassium, calcium, barium; replacement of magnesium with Ti, Fe, Mn, Cr; fluorine substitution OH, a variant of a manganese phlogopite mica, mica titanium, chromium mica, fluorine phlogopite and so on. The performance characteristics of the use of features produced.
