Spinel type composite ultrafine blue ceramic pigment and preparation method thereof
The invention belongs to the technical field of ceramic pigments, and specifically relates to a preparation method of a spinel type composite ultrafine blue ceramic pigment. The preparation method comprises the following steps: (1) dissolving CoAl2O4 into water to obtain a solution (A); (2) evenly mixing butyl titanate with anhydrous ethanol with a volume 2 to 3 times of that of butyl titanate to obtain a solution (B); (3) adding the solution (B) into the solution (A) under stirring, stirring the mixed solution at a room temperature for 5 hours or more, and allowing the mixed solution to stand still to carry out aging for 24 to 48 hours so as to obtain opaque gel; (4) drying and grinding the opaque gel obtained in the step (3) to obtain loosened precursor powder, transferring the precursor powder to a muffle furnace, and burning the precursor powder in the muffle furnace for 4 to 6 hours at a temperature of 400 to 500 DEG C so as to obtain the blue ceramic pigment. The prepared spinel type composite ultrafine blue ceramic pigment combines the excellent performances of CoAl2O4 and TiO2 and has the advantages of good thermal stability, high chemical stability, bright color and luster, and unchanged color at a high temperature.
