Zirconium kalium phosphate type high temperature purple ceramic pigment and preparation method

Abstract

The invention relates to a zirconium phosphate kalium type high-temperature purple ceramic colorant and a preparation method thereof. The colorant is made from industrial chemical raw materials in percentage by weight: 4 to 12 percent of potash, 49 to 58 percent of diammine phosphate, 32 to 37 percent of zirconia, and 2.6 to 7 percent of cobalt oxide. A product is obtained through batching, mixing, calcining, crashing, washing, drying, crashing and drying, wherein a calcining temperature is 1400 DEG C and is kept for 60min. The method adopts usual chemical raw materials with lost cost. The obtained colorant with brilliant coloration and stability can be widely applied to various high-temperature ceramic products.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a potassium zirconium phosphate type high-temperature purple ceramic colorant and a preparation method thereof. Background technique [0002] The development of ceramics has experienced thousands of years of history, and ceramic products have combined practicality and ornamental value since they came out. From the painted pottery of Longshan culture to various famous porcelains in the heyday of ancient ceramics, all of them embody the culture of various historical periods and are the crystallization of the wisdom of the ancient working people. The glaze and color used to decorate these traditional ceramics are the essence of these treasures. However, due to the limitation of the level of science and technology at that time, people can only use natural minerals as coloring materials, and the repeatability of coloring is extremely poor. In th...

Problems solved by technology

Low-temperature pigments have a wide variety of colors. However, since each pigment has a limit use temperature, when the temperature exceeds this temperature, the crystal structure of the pigment is in an unstable state, and it is easy to be melted or react with other substances and cannot be displayed. Pure color, therefore, there are relatively few pigments with stable color at high temperature, and there is a shortage of color types, and pigments that can develop color at extremely high temperatures (greater than 1400°C) are even rarer.

Potassium zirconium phosphate ceramic material is a new type of low-expansion material. Because of its high strength, thermal shock resistance, and high temperature resistance, it has important application values ​​in aerospace, automotive industry, and nuclear waste fixation. It has become a key material that people pay attention to and has been studied in depth, but its application in the field of high-temperature ceramic pigments has not been reported
