Mechanical Properties

Mica is transparent, relatively soft, optically flat, easily split table into thin films along its cleavage, colorless in thin sheets, resilient and incompressible.

Mica has extraordinary mechanical properties. It has very good compression resistance, good tensile and bending strength and large elasticity modulus. It is flexible, elastic and tough, having high tensile strength. It can withstand great mechanical pressure perpendicular to plane.
