Abstract

The invention relates to a high-temperature-resistant purple rare-earth ceramic pigment and a preparation method thereof. The high-temperature-resistant purple rare-earth ceramic pigment with the molecular formula of NdAlO3.Y0.5ErAlO3 is prepared from raw materials including industrial neodymium oxide, erbium oxide, yttrium oxide and aluminum oxide, has pure and uniform color and can resist high temperatures. In the ceramic pigment, rare earth elements including neodymium, erbium and yttrium act with an aluminum element, the color effect produced through high-temperature firing is combined with a ceramic material, the very natural artistic texture effect is obtained, and the artistic aesthetic value is very high. Prepared glaze has glossy and bright glaze surface and can reduce cracks. Various tableware, tea sets and other daily products prepared from rare-earth ceramic have jade-like soft and glossy appearance and show nobleness and taste. Besides, the purple rare-earth ceramic pigment has a remarkable color effect, stable performance and very high practical application value after applied to ceramic artworks.

Description

technical field

[0001] The invention belongs to the technical field of ceramic pigments, in particular to a high-temperature-resistant purple rare earth ceramic pigment and a preparation method thereof. Background technique

[0002] Ceramic glaze is an important raw material that must be used in the production of ceramics. It has a strong protective effect on the ceramic body. At the same time, the physical properties of silicate make the glass enamel on the ceramic surface effectively resistant to acid and alkali corrosion. Very good antibacterial properties. Ordinary ceramic color glazes add ceramic pigments to the glass enamel to achieve color development during the firing process. The existing ceramic pigments are often single in color, which cannot highlight the artistic beauty and high temperature of the ceramic color glaze itself. The special artistic effect produced during the firing process.

[0003] High-temperature colorants refer to colorants whose use temperat...
