摘要: Metal ions doped complex cobalt blue pigments are prepared by homogeneous precipitation, to investigate the effects of doping Zn2+ ,Mg2+ ,Ni2+ and Y 3+ on some properties pigments, such as crystal structure, color, shading power temperature resistance. Studies have shown that little effect spinel type resistance ; ionic radius differences between Co2 + cause lattice distortion changes constant , thus affecting ligand state spaces ion, color pigment. The Zn2 becomes larger with increasing amount while Mg2 +and Ni2 constants become smaller; when Y3 enter into CoAl2O4 lattice, replacing hexa-coordinate octahedral gap Al3 Al3+cause distortion, 3 increases a certain extent, phase in form Y2O3 will be generated it maybe kind CoYxAl2-xO4- solid solution instead complete structure.
