Pearlescent pigment with the properties of high crystallinity, good dispersity, no agglomeration and smooth and crackless surface was prepared by hydrothermal method instead of calcination in the present paper. Through observation, rules of preparing high performance pearlescent pigment were obtained, described as follows: Increment of temperature and elongation of time during the period of hydrothermal reaction was beneficial to the crystallization of pearlescent pigment. Herein, coating and luminescence mechanism of pearlescent pigment was taken into further investigation.
