Physical and chemical characteristics of Muscovite
Because the properties of mica and mica powder itself, mainly has the following purposes: daily chemical raw materials, ceramic materials, paint filler mica, plastic and rubber additives, building materials, for protection layer, electrode for drilling mud additive,Bai Yunmu, which belongs to the silicon acid salts, chemical formula: KAl2 (AlSi3010) 2 (OH), monoclinic, hardness of 2.5 - 4, the proportion of 2.77 - 2.88 in the natural environment, often with a plate surface six False crystal, flaky or scaly.
Muscovite is characterized by its insulation, high temperature resistance, gloss, stability in physical and chemical properties, good heat insulation, elasticity and toughness. After processing into mica powder, there is better sliding and strong adhesion.
Color from colorless to white, sometimes with green, brown streak, colorless, with a very complete joint. Hardness: up to 2-3, vertical to 4Specific gravity: 2.76-3.10g/cm 3Cleavage: cleavage extremely complete, with (110) and (010) splittingColor: light yellow, light green, light red or red brownTransparency: transparent to translucentLuster: Glass luster, pearl luster on cleavage surfaceOther: flake with remarkable elasticity. Insulation and heat insulation are exceptionally strong, glass or pearl luster. There are very good cleavage of the bottom surface, so often a piece of mica can be torn down.
