Mica is used in plastic automobile fascia and fenders as a reinforcing material, providing improved mechanical properties and increased dimensional stability, stiffness, and strength. Mica-reinforced plastics also have high-heat dimensional stability, reduced warpage, and the best surface properties of any filled plastic composite.
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with Shimazaki H, Shigeoka M, Yokoyama K, Matsubara S, Yurimoto H (2011) Yangzhumingite, KMg2.5Si4O10F2, a new mineral in the mica group from Bayan Obo, Inner Mongolia, China.

The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Layering in the univalent (potassium, sodium), or true, micas imparts perfect basal cleavage, allowing crystals to be split into very thin sheets that are tough and flexible. Layering in the

Mica, any of a group of hydrous potassium, aluminum silicate minerals. It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure. Among the principal rock-forming minerals, micas are found in all three major rock varieties—igneous, sedimentary, and metamorphic.
Muscovite is the most common form of mica. Its name is derived from "Muscovy Glass", which describes thick sheets of transparent mica that were once used as a glass substitute in Russia. Because of Muscovite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals.
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 sheets have a pearly to vitreous luster on their surface.
Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula K(Mg,Fe) 3 AlSi 3 O 10 (F,OH) 2. It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite and eastonite.
Mica is the name given to a group of silicate minerals that have silicon and oxygen as their two major components. The Mica family of minerals includes several variations based on chemical composition and characteristics.
Mica is bestand tegen constante temperatuur van 550 °C (smeltpunt ca. 1250 °C) en is bovendien enigszins tot volledig doorzichtig, afhankelijk van de kwaliteit. Het materiaal werd daarom vooral vroeger gebruikt als venster in een kolenkachel en in petroleumkachels.
Mineral Resource of the Month: Mica Jason Christopher Willett, a mineral commodity specialist for the U.S. Geological Survey,compiled the following information on mica. Sheets of muscovite and biotite mica litter the ground at the Ruggles Mine in Grafton, N.H., where mica was discovered in 1803.
Mica in Cosmetics. Most of the health effects of mica are caused by exposure to the large amounts typically present at industrial work sites. However, mica is a common ingredient in mineral makeup, and products that use ultra-fine nanoparticles in their ingredients carry the risk of inhalation.
Utilisation sous forme de papier mica. Le mica est utilisé pour ses propriétés d'isolant électrique et de résistance à la chaleur. Industriellement, le mica est mis en pulpe dans de l'eau, puis transformé en papier mica (à l'aide de machines identiques aux machines à papier classique).
The Minerals Education Coalition’s (MEC) mission is to inform and educate K-12 students and the public about the importance of minerals and mining.

Mica Properties and Meaning. Mica is a member of the Silicates family. It is a very shiny crystal and is a common companion for other minerals like Tourmaline, Aquamarine, Fuchite and Aventurine. Read more about Mica crystal healing properties below, with photos and desktop image!
WHO. The MICA project brings together a multidisciplinary team of experts from natural and technical sciences, social sciences including political sciences, and information science and technology to ensure that Raw Material Intelligence is collected, collated, stored and made accessible in the most useful way corresponding to stakeholder needs.
Biotite is a very common form of mica. It is named in honor Jean Baptiste Biot (1774 1862), a French physicist, mathematician, and astronomer who researched the mica minerals for their optical properties. Because of Biotite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to
The mineral mica is abundantly used in items that you use everyday, like cosmetics and electrical appliances. This is because of the unique properties it possesses. We shall furnish the properties and uses of mica for your understanding.
Mica is the general name given to a group of 37 crystalline silicate minerals. Mica can be ground into small flakes and added to paints to make them shiny and iridescent. According to the Mineral Information Institute, the word "mica" is related to the Latin word "micare," which means "to shine."
