Abstract
The invention discloses low-temperature cadmium-selenium red glazepowder and a preparation method and application thereof. The preparation method of the low-temperature cadmium-selenium red glazepowder comprises the steps: performing dry grinding on red lead, boric acid, quartz, cadmiumcarbonate, borax and kaolin, and preparing a mixture; grinding the mixture into powder, calcining for the first time, cooling with water, carrying out wet grinding, sieving, drying, and grinding into powder again to obtain low-temperature frit powder; carrying out dry grinding and mixing on the low-temperature frit powder, kaolin, zirconiumoxide and a cadmium-selenium red pigment, then carrying out powdering, secondary calcination, water cooling, wet grinding, sieving, drying, and then carrying out powdering again so as to obtain low-temperature cadmium-selenium red glaze powder; with the steps of optimizing a formula of a low-temperature frit, carrying out wet grinding on the low-temperature frit toprepare frit powder, carrying out uniform dry grinding on the frit powder and a cadmium-selenium red pigment, calcining, carrying out water quenching, carrying out wet grinding to obtain low-temperature cadmium-selenium red glaze powder, and carrying out the secondary sintering process to fully volatilize volatile matters in the low-temperature cadmium-selenium red glaze powder, pores are not generated when the low-temperature cadmium-selenium red glaze powder is applied to glass and enamel, the color of the glaze surface is brighter, and the glossiness is higher.
Description
technical field [0001] The invention relates to the technical field of glaze powder and its preparation method and application, in particular to a low-temperature cadmium selenium red glaze powder and its preparation method and application. Background technique [0002] The bright red has always been loved by the Chinese people. The bright red pigments currently on the market are mainly composed of zirconiumsilicate wrapped with cadmium sulfurselenide, but the heat resistance of this pigment is insufficient during the heat treatment process, and it begins to oxidize and decompose at around 500°C. It is easy to fade under high temperature, and the color is not deep red enough, and some pigments are not even resistant to temperature, resulting in bubbles or orange glaze on the glaze. The low-temperature red glaze powder on the market can get bright red. The common preparation method is to prepare low-temperature frit glaze powder first, and then mix the low-temperature frit ...
