The Interesting Properties and Common Uses of the Mineral Mica

Feb 28, 2018· The mica group is a group of phyllosilicate minerals. Its atoms are arranged in a hexagonal manner. That is why it displays basal cleavage. All the minerals belonging to the mica group can be classified by the formula: X 2 Y 4-6 Z 8 O 20 (OH, F) 4 in which, X is K, Na, or Ca. Rarely, it can also refer to Ba, Rb, or Cs; Y is Al, Mg, or Fe.
