Mica is generally applied to aluminosilicate minerals that have flaky and plate- like structure in nature with different Physical properties and Chemical compositions. The significant crystal structure of the Mica permits the mineral to be split into optically flat films as thin as 1µm in some cases. Muscovite, Biotite, Phlogopite, Vermuculite, Lepidolite, Zinnwaldite , and Roscoelite are the commercially important Mica Minerals. The main Azar Talgh Mica Product is Phlogopite and its chemical composition and properties is according to the following:
