Preparation method of Cr-doped CaTiO3 yellow ceramic pigment, products prepared by using preparation method and applications
The invention discloses a preparation method of a Cr-doped CaTiO3 yellow ceramic pigment, which comprises the following steps: dissolving butyl titanate into ethanol so as to obtain liquid A; dissolving calcium chloride dihydrate and chromic nitrate into distilled water, and mixing the obtained mixture with ethanol so as to obtain liquid B; stirring and mixing the liquid A and the liquid B, and adding the obtained mixture into an alkaline regulator, so that the pH value of the mixed solution system is 12; further stirring, putting the obtained object into a hydrothermal kettle, and carrying out heat preservation for 1-36h at a temperature of 180-260 DEG C, so that the Cr-doped CaTiO3 yellow ceramic pigment is obtained. In addition, the invention also discloses products prepared by using the preparation method and applications. According to the invention, the properties and use of a CaTiO3 material as a ceramic pigment are developed and expanded, and the CaTiO3 material is prepared in a low cost, which facilitates the promotion of the application and development of CaTiO3 material and ceramic pigment production technologies.
