Abstract

The advanced methods for synthesis of the nanocrystalline cobalt aluminate spinel powder (CoAl2O4) was analyzed for subsequent coloration of composites in the ZrO2—Y2O3—CeO2—Al2O3—СоО system. It was found the effect of the precursor and heat treatment for the color and properties of synthesized CoAl2O4 powders. A variety of current synthesis steps provides the producing of nanocrystalline CoAl2O4 with a green or blue coloration with a wide range of the primary particles size distribution at different temperatures. Finally the choice of method is determined by the specific varying conditions of the composite using.
