Basic potassium lithium aluminum fluoro-silicate. WHAT TO LOOK FOR ON THE … Continued The Mica family of minerals includes several variations based on chemical composition and characteristics.

Chemical Formula. Mica is the name given to a group of silicate minerals that have silicon and oxygen as their two major components. MICA, a generic term, refers to any of a group of approximately 30 silicate minerals occurring as non-fibrous plates. These minerals can be classified on the basis of variations of chemical composition and atomic structure into nine groups: (1) kaolin-serpentine (kaolinite, halloysite, lizardite, chrysotile), (2) pyrophyllite-talc, (3) mica (illite, glauconite, celadonite), (4) vermiculite, (5) smectite (montmorillonite, nontronite, saponite), (6) … It has a specific chemical formula, and is crystalline in structure. A mineral is an inorganic solid found in nature. Graphite. Muscovite is a potassium-rich mica with the following generalized composition… KAl 2 (AlSi 3 O 10)(OH) 2. The etymology of the word mica can be traced to the Latin word ‘mica’, which means a crumb, and it may also have been derived from another word ‘micare’, which means to glitter. [1] FOUND IN: Makeup products, shingles, wallpaper, insulation, cement and asphalt. Muscovite Chemical Composition. A pink variety of the related mica mineral Muscovite can be identical in appearance to Lepidolite, and is many times incorrectly labeled as Lepidolite. 116the general formula for minerals of the mica group is xy 2 3 z 4 o 10 (oh, f) 2 with x k, na, ba, ca, cs, (h 3 o), (nh 4 ); Y al, mg, fe 2, li, cr, mn, v, zn; And z si, al, fe 3, be, ti. Muscovite (hydrated aluminium potassium silicate[KAl2(AlSi3O10)(F, OH)2 ])and phlogopite (potassium magnesium aluminum silicate hydroxide) are the two major micas of commerce.

The general chemical formula for most micas is W(X, Y)2–3Z4O10(OH, F)2. Graphite is not a mica but a metallic mineral. It also cleaves into inelastic brittle flakes rather than the thin flexible sheets of phlogopite and biotite. Mica is a naturally occurring mineral dust often used in makeup foundations, as filler in cement and asphalt, and as insulation material in electric cables. It can be found in massive crystal layers weighing several hundred pounds. Color. Approximate chemical formula K (Mg, Fe). 816 mica chemical formula products are offered for sale by suppliers on Alibaba.com, of which dyestuff intermediates accounts for 1%, oxide accounts for 1%. Biotite is the most common mica mineral and also known as black mica, a silicate mineral in the common mica group. Below are just three of at least 11 common variations: Biotite; muscovite; boromuscovite K (Li,Al)3(Si,Al)4O10(F,OH)2. Aluminum is sometimes replaced by magnesium, iron, lithium, chromium, or vanadium. Workers in cosmetic manufacturing factories are at high risk of mica exposure through inhalation. In this formula potassium is sometimes replaced by other ions with a single positive charge such as sodium, rubidium, or cesium. Chlorite is another mica mineral that might be confused with phlogopite, but chlorite usually has a very distinctive green color. Approximate chemical formula K (Mg, Fe). Composition. A wide variety of mica chemical formula options are available to you, such as chemical auxiliary agent.
