Abstract�� Coloring mica nacreous pigments were prepared by double-covering method, and the optimum parameters were given for cobalt-colored and nickel-colored, respectively. In case of cobalt-colored mica nacreous pigment, the optimum technical conditions are: hydrolyzed at 100 �� for 2 h, pH 7—8, the volume of cobalt nitrate is 25—30 mL to 10 g raw material��finally calcined at 600 �� for 1.5 h. In case of nickel-colored mica nacreous pigment, the optimum technical conditions are: hydrolyzed at 90 �� for 2 h, pH 7—8, the volume of nickel dichloride is 20 mL to 10 g raw material��finally calcined at 600 �� for 1.5 h.
Keywords�� double-covering method   coloring mica nacreous pigment   cobalt and nickel coloring
