Abstract：
 Disclosed is a process for synthesizing Cl-O-Bi nano pearly luster pigment, which comprises using bismuth nitrate as raw material, charging surface active agent hexadecyl ammonium chloride for reaction, controlling the mol ratio of tervalency metallic bismuth ion and hexacontane ammonii chloridum to be 0.1-1:2, adjusting pH of the solution to be 1-14 with NaOH solution, for hydrothermal reaction at 120-200 deg C.
