The perfect cleavage into thin elastic sheets is probably the most widely recognized characteristic of the micas. The cleavage is a manifestation of the sheet structure described above. (The elasticity of the thin sheets distinguishes the micas from similarly appearing thin sheets of chlorite and talc.)
How do you make mica sheets?To produce mica in composite sheet form, it must be ground down into divided particles. This involves using a hammer mill or similar micro-pulverising equipment. Then these particles must be combined with water. A colloid substance may be added.
