Microwave mica in stock write call

The layered structure of mica and the weak bond between the packets affect its properties: lamellarity, very perfect (basal) cleavage, the ability to split into extremely thin sheets that retain flexibility, elasticity and strength. Mica crystals can twin according to the "mica law" with the intergrowth plane (001) and often have pseudo-hexagonal outlines. The hardness of mica on the mineralogical scale is 2.5-3, the density is 2770 kg/m? (muscovite), 2200 kg/m? (phlogopite), 3300 kg/m? (biotite). Muscovite and phlogopite are colorless and transparent in thin plates, shades of brown, pink, green are due to impurities of Fe2+, Mn2+, Cr2+ and other ions. Ferrous micas are brown, brown, dark green and black, depending on the content and ratio of Fe2+ and Fe3+. Micas have good electrical insulating properties.
