Photoelectric: PE Muscovite = 2.39 barns/electron U=PE Muscovite x r electron = 6.72 barns/cc Specific Heat: 0.21 Optical Axial. Except for large and resistant specimens, Muscovite is very hard to clean because if washed it will absorb water internally and start to break apart. The best way to wash Muscovite and other Micas is with a dry electric toothbrush MICA, a generic term, refers to any of a group of approximately 30 silicate minerals occurring as non-fibrous plates. Muscovite (hydrated aluminium potassium silicate[KAl2(AlSi3O10)(F, OH)2 ])and phlogopite (potassium magnesium aluminum silicate hydroxide) are the two major micas of commerce. Micas are commonly found in ordinary rocks
Muscovite is the most common mineral of the mica family. It is an important rock-forming mineral present in igneous , metamorphic , and sedimentary rocks . Like other micas it readily cleaves into thin transparent sheets Muscovite Chemical Composition. Muscovite is a potassium-rich mica with the following generalized composition KAl 2 (AlSi 3 O 10)(OH) 2.

Minerals. calcite: hardness = 3 (not very hard), 3 cleavages not 90°, fizzes in dilute HCl. quartz: hardness = 7 (hard), conchoidal fracture. micas: flake off in thin sheets. muscovite: clear or light colored mica biotite: black (mafic) or dark colored mica. feldspars: hardness = 6 (hard), 2 cleavages at 90°. potassium feldspar (k-spar): perthite (wavy lines The mica minerals have one perfect cleavage that allows them to be broken into very thin sheets. This is very distinctive. Muscovite is clear, silvery, or coppery silver in color (depending on the thickness of the sample and presence of impurities) whereas fresh biotite is black. When biotite weathers, it can become dark golden or coppery in color Hardness: 2 ½ Density: 2.77-2 Sericite is name given to very fine, ragged grains and aggregates of white mica - usually muscovite - produced by the alteration of feldspars or other minerals. Included grains of zircon or other radioactive minerals may form pale pleochroic halos in surrounding muscovite Mica is widely distributed and occurs in igneous, metamorphic and sedimentary regimes. Large crystals of mica used for various applications are typically mined from granitic pegmatites.. The largest documented single crystal of mica was found in Lacey Mine, Ontario, Canada; it measured 10 m × 4.3 m × 4.3 m (33 ft × 14 ft × 14 ft) and weighed about 330 tonnes (320 long tons; 360 short tons) Muscovite Muscovite is a member of the mica group of silicate minerals (sheet silicates) in which the base of all of the SiO 4 tetrahedra lie in one plane and three corners of the base are shared with the neighbouring tetrahedra. This creates a strongly layered sheet-like structure, hence the term sheet silicate (the sheets are weakly bound together by layers of potassium ions)
Muscovite's hardness is rated between a two and a three. This is rather soft on the scale used to measure mineral hardness. Falling on the low end of the hardness scale means it can be easily scratched by common objects, such as a penny or a fingernail B & M Mica Co has been providing high quality mica products to various industries all over the world since 1975.
