Mica

详情

Mica is naturally occurring mineral, based on group of silicate minerals composed of varying amounts of aluminium, potassium, magnesium, iron and water having sheet-like or plate-like structure with different composition and physical properties. All Mica form flat six sided monoclinic crystal with remarkable cleavage in the direction of large surfaces, which permits them to be easily cleaved into optically flat films. When cleaved into thin films, they remain tough and elastic even at high temperatures.
Mica is also known as Muscovite, Biotite, Phlogopite and Lepidolite.
