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.
Talc, or talcum, is a clay mineral composed of hydrated magnesium silicate, with the chemical formula Mg 3 Si 4 O 10 (OH) 2.Talc in powdered form, often combined with corn starch, is used as baby powder.
Kirazuri (雲母摺り) is a method used in Japanese woodblock printmaking using mica powder, or 雲母 (kira) to add sparkle. When used for the background in portraits, depending on the base color, it is called Shiro-kirazuri (white), Kuro-kirazuri (literally black, but dark gray practically), and Beni-kirazuri (red). [1]
Sericite also occurs as the fine mica that gives the sheen to phyllite and schistose metamorphic rocks. The name comes from Latin sericus , meaning "silken" in reference to the location from which silk was first utilized, which in turn refers to the silky sheen of rocks with abundant sericite.
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]
A powder is a dry solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, ...
The most usual source of pearlescence is the natural mineral mica covered by a thin layer of titanium dioxide. This coating causes goniochromism – the color appears through interference effects with the naturally translucent mica, and varying the thickness of the titanium dioxide changes the color. [8]
