Synthetic mica is produced through the processes of raw material selection, high temperature to dissolve system, crystal formation, microcrystalline processing based on natural mica’s crystal morphology, chemical composition and physical performance. Synthetic mica is not only high purity, good whiteness but also has high compressive strength, high resistance to change intensity, high breakdown strength resistance compared to natural mica.
