Inorganic pearlescent pigments

Inorganic pearlescent pigments mainly include high mercury chloride, basic lead carbonate, acid lead arsenate, acid lead phosphate, and bismuth hydroxide. However, such pearlescent pigments are either potentially toxic or have poor chemical stability, which limits their application range.

Mica-based pearlescent pigments

Natural mica is an excellent base material for the preparation of mica pearlescent pigments, and is widely used because of its abundant resources and low manufacturing cost. Mica-titanium pearlescent pigments are the most widely studied and most mature type of pearlescent pigments. Due to the different refractive indices of titanium dioxide and mica substrates, pearl effect, color effect and goniochromatic effect are produced through the multiple reflection and interference of light.

With the continuous deepening of research on pearlescent pigments, some other matrix materials have also been discovered and used in the preparation process of pearlescent pigments, such as glass-based pearlescent pigments, aluminum flake-based pearlescent pigments, oxide-based pearlescent pigments, kaolin, ceramics flakes, graphite flakes, etc.
