What is the basis of inorganic material science?
Mica belongs to aluminium silicate. The mica with good quality has high light transmittance, small dielectric constant, lamellar structure and easy dissociation.
The surface of the mica plate after dissociation is closed and the interface formed will not disappear;
Thus the light reflector; the reflected light and incident light will be in the interface (stripping strip) on the generation of optical interference. Rainbow colored interference patterns will emerge.
