Common micas include biotite, lepidolite, muscovite, phlogopite and zinnwaldite. Muscovite mica is a phyllosilicate mineral of aluminum and potassium with the formula KAl2(AlSi3O10)(F,OH)2, or (KF)2(Al2O3)3(SiO2)6(H2O). It has a highly-perfect basal cleavage yielding remarkably-thin laminae (sheets) which are often highly elastic.

Pure muscovite mica has a dielectric strength of 2000 volts per millimetre - meaning it's very good at withstanding high voltages. Working with high voltages often means high temperatures, and the risk of fire. Again, mica-based composite insulation solutions can withstand up to 1600 Degrees C, and mica is non-combustible.

Dehydrated muscovite is the transformed structure of phlogopite at high temperature [11]. As mentioned before, C37 was not crystallized at 700 °C by MW heating but obtained a high density ( Fig. 6 ). It is very likely that the OH − groups of muscovite and glass absorb microwave energy at early stages of heating and increase the temperature.
