The preparation methods of mica board pigments mainly include gas phase method and liquid phase method.

The gas phase method uses gaseous precursor reactants to form a thin film on a mica substrate to prepare pearlescent pigments. The coated mica is synthesized by chemical vapor deposition. Titanium dioxide is a powder produced by the reaction of titanium tetrachloride and ethyl acetate.
