高达10%返现Muscovite was ground in water, alkaline chloride solutions, methanol and toluene. The influence of the grinding medium was investigated using several methods, in particular by electron microscopy. It was found that the addition of lithium ions in aqueous media or NH 3 to methanol facilitates the breakdown of the muscovite structure.

ContactA method of dry grinding muscovite based on the use of knife-mills is reported. It was possible to produce mica with a particle size below 100 and 45 μm. After grinding, the samples were submitted to sonication treatment, which promoted delamination of the material.
ContactMuscovite can come in enormous crystal groupings that can weigh several hundred pounds. Thin sheets can be peeled off as layers, and the thinner a layer is peeled the greater its transparency becomes. 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.
ContactMuscovite 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 sheets have a pearly to vitreous luster on their surface.

ContactThe stand-alone name 'Muscovite' was used as early as 1794 by Johann Gottfried Schmeisser in his System of Mineralogy and is derived from the term "Muscovy glass," which was in common use by that time. Muscovy Province in Russia yielded sheet mica for a variety of uses.

ContactMuscovite has a Mohs hardness of 2–2.25 parallel to the [001] face, 4 perpendicular to the [001] and a specific gravity of 2.76–3. It can be colorless or tinted through grays, browns, greens, yellows, or (rarely) violet or red, and can be transparent or translucent. It is anisotropic and has high birefringence. Its crystal system is monoclinic.

ContactMuscovite is the pure potassium mica.. Muscovite is colorless, and it has no impurities replacing elements in its crystal structure. There are several muscovite mica varieties including lepidolite and fuchsite.. When muscovite occurs with natural green color due to chromium impurities replacing aluminum in the mica crystal structure is known as fuchsite mica.
ContactMuscovite is an extremely common mineral, nevertheless there are some exceptional localities that need to be mentioned. Outstanding Muscovite crystals, some bright yellow and others with perfect star formations, come from the famous pegmatite localites in the Doce and Jequitinhonha Valleys in Minas Gerais Brazil.
