Mica is used in plastic automobiles 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.
MHC class I polypeptide–related sequence A (MICA) is a highly polymorphic cell surface glycoprotein encoded by the MICA gene located within MHC locus. [5] MICA is related to MHC class I and it has similar domain structure, however, it is not associated with β2-microglobulin nor binds peptides as conventional MHC class I molecules do. [ 6 ]
Muscovite (also known as common mica, isinglass, or potash mica [6]) is a hydrated phyllosilicate mineral of aluminium and potassium with formula KAl 2 (AlSi 3 O 10)(F,OH) 2, or 2 (Al 2 O 3) 3 (SiO 2) 6 (H 2 O). It has a highly perfect basal cleavage yielding remarkably thin laminae (sheets) which are often highly elastic.
Fuchsite, also known as chrome mica, is a chromium (Cr)-rich variety of the mineral muscovite, belonging to the mica group of phyllosilicate minerals, with the chemical formula K(Al,Cr) 3 Si 3 O 10 (OH) 2. [2] Trivalent chromium replaces one of the aluminium (Al) atoms in the general muscovite formula producing the apple green hue distinctive ...
Examples include sillimanite, kyanite, staurolite, andalusite, and some garnet. [15] Other minerals, such as olivines, pyroxenes, hornblende, micas, feldspars, and quartz, may be found in metamorphic rocks but are not necessarily the result of the process of metamorphism. These minerals can also form during the crystallization of igneous rocks ...
The mineral mica was commonly used at that time for electrical insulation. Because the new product acted as a substitute "for mica", Faber used the name Formica [1] as a trademark. The word already existed as the scientific name for wood ants, from which formic acid and the derivative formaldehyde compound used in the resin were first isolated.
Mica. Glittering surfaces have been found to be used since prehistoric times in the arts and in cosmetics. The modern English word "glitter" comes from the Middle English word gliteren, possibly by way of the Old Norse word glitra. [10] However, as early as 30,000 years ago, mica flakes were used to give cave paintings a glittering appearance. [1]
Glauconite is an iron potassium phyllosilicate (mica group) mineral of characteristic green color which is very friable [5] and has very low weathering resistance.. It crystallizes with a monoclinic geometry.
