Preparation method of purple ceramic pigment with cobalt-silicon olivine structure
The invention discloses a preparation method of a purple ceramic pigment with a cobalt-silicon olivine structure. The preparation method comprises the following steps: tetraethoxysilane and cobalt chloride hexahydrate are taken as main raw materials to prepare sol under the water-bath heating condition according to different cobalt-silicon ratios, and the sol is calcined within the wider temperature range of 1000-1300 DEG C through adding a mineralizer and adjusting the pH value of the system, so that the purple ceramic pigment with the Co2SiO4 olivine crystal structure is obtained. Compared with the traditional solid-phase method, the synthetic method has the characteristics of being simple in technology, low in equipment requirement, convenient to operate, and low in synthesis temperature, the ball milling process is not required, and the pollution caused by impurities is avoided, so that the preparation method has a wide market space.
