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.
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.
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.
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 ]
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 ...
Roscoelite is a green mineral from the mica group that contains vanadium. The chemical formula is K(V 3+, Al, Mg) 2 Al Si 3 O 10 (OH) 2. [2] Crystals of roscoelite take on the monoclinic form, and are from the 2/m point group. The appearance is semi transparent to translucent coloured olive brown to green brown. The lustre is pearly.
Structure of illite mica – USGS [5]. Illite, also called hydromica or hydromuscovite, [6] is a group of closely related non-expanding clay minerals. Illite is a secondary mineral precipitate, and an example of a phyllosilicate, or layered alumino-silicate.
These particles are often made of the mineral mica. Mica is resilient, reflective, refractive, dielectric, chemically inert, insulating, lightweight, and hydrophilic. [1] Alternatively, aluminium or bronze powder may be used. To make the "hammered" effect more pronounced, a small amount of silicone oil may be added directly before application.
