Abstract

The invention discloses a preparation method of a silver red ceramic pigment, wherein the method comprises the following steps: preparing an acid solution, preparing an alkali solution, carrying out acid-base titration to obtain a precipitate, and carrying out suction filtration, washing, drying, ball milling, calcining, grinding, drying and screening on the precipitate to obtain the finished product. The silver red pigment is prepared by adopting a coprecipitation method, through various chemical reactions in the solution, the prepared reaction precursor is uniform in chemical components, small in granularity and uniform in distribution, the firing temperature of the raw materials can be greatly reduced, and the fired pigment is more uniform in particle distribution and better in color development intensity.

Description

technical field [0001] The invention relates to the technical field of ceramic inorganic pigments, in particular to a preparation method of silver red ceramic pigments. Background technique [0002] Among ceramic pigments, pink has always been popular with consumers. Traditional pink pigments include chrome-aluminum red, agate red, and manganese red, but the pigments are either not bright enough in color, insufficient in color strength; or poor in high temperature resistance; or It can only be colored in a special glaze, so its application is greatly restricted, and it is difficult to meet the needs of the market. At present, the new pink ceramic pigments include golden red and silver red, which are bright and bright pink. However, the preparation cost of golden red is high, and its high temperature resistance is poor, so its application is limited. Silver red is more worth exploring. At present, the methods for preparing silver-red ceramic pigments are mostly solid-phase m...
