  2. Mica - Wikipedia

    en.wikipedia.org/wiki/Mica

    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.

  3. MHC class I polypeptide–related sequence A - Wikipedia

    en.wikipedia.org/wiki/MHC_class_I_polypeptide...

    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 ]

  4. Muscovite - Wikipedia

    en.wikipedia.org/wiki/Muscovite

    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.

  5. Fuchsite - Wikipedia

    en.wikipedia.org/wiki/Fuchsite

    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) 2 (AlSi 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 ...

  6. Formica (plastic) - Wikipedia

    en.wikipedia.org/wiki/Formica_(plastic)

    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.

  7. Glitter - Wikipedia

    en.wikipedia.org/wiki/Glitter

    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]

  8. Metamorphism - Wikipedia

    en.wikipedia.org/wiki/Metamorphism

    The black crystal is garnet, the pink-orange-yellow colored strands are muscovite mica, and the brown crystals are biotite mica. The grey and white crystals are quartz and (limited) feldspar . Metamorphism is the transformation of existing rock (the protolith ) to rock with a different mineral composition or texture .

  9. Bird's eye extinction - Wikipedia

    en.wikipedia.org/wiki/Bird's_eye_extinction

    Granite sample under cross polarized light containing plagioclase, quartz, and mica. The mica in orange here exhibits the bird's eye extinction pattern. Bird's eye extinction , or bird's eye maple , is a specific type of extinction exhibited by minerals of the mica group [ 1 ] under cross polarized light of the petrographic microscope .
