The application of rare earth in functional ceramics

In recent years,along with the development of material science, people have paid much attention to composite ceramic function.Research on development of adding the rare earth to function composite ceramic have made great progress. Intelligent ceramics is one of function composite ceramic that can automatic diagnosis, self-adjustment, recovery etc. As mentioned,adding rare earth to lead zirconate titanate (PZT) can obtain lead lanthanum zirconate titanate (PLZT).It is not only a good lightning ceramics, and because of its shape memory function, which reflects the shape of the self recover from tuning mechanism,but also a kind of intelligent ceramics.

The concept of intelligence ceramic materials, advocating a new concept of developed and designed the ceramic materials.It is beneficial to broaden the rare earth in modern functional ceramics. In recent years, the study also shows that, rare earth in biological ceramics, antibiotic ceramic and so on the new ceramic material also has unique role. Because of rare earth elements can synergistic with silver, zinc, copper and other transition element, the development of rare earth compound phosphate antibacterial can make a significant amount of hydroxyl radicals on the surface of ceramic, thereby enhancing the antibacterial properties of ceramic.

We have to put the rare earth into good ues. We need to further strengthen the research on affection of adding the rare earth to function ceramic. And strengthen the development of new functional ceramics.Effectively improve the application of rare earth in high-tech material value.

Rare earth ceramic pigment is mainly refers to the combination of five kinds of hue shading zirconium stones and rare earth ceramic pigment. It can be used as the building ceramic decoration materials of CaiYouZhuan, wall brick, floor tile etc.It is especially suitable for decorated of sanitary ware ceramics products.It also can be used as color key of porcelain glazes glair colour and glaze color. Color combination zirconium stones and rare earth ceramic pigment, zirconium dioxide and silica is for matrix materials to transition elements and rare earth elements for combination colorants, adding a bit of mineralization agent, after the high temperature of 900 -1150 ¡æ solid instead should synthesis. The main technical indexes as follows: hue have red, yellow, blue, green and gray, stability is less than or equal to 1280 ¡æ maximum of 1300 ¡æ, to adapt to the atmosphere for YangHuaYan, particle diameter less than 15 ¦Ì m not less than 92%, more than 30 ¦Ì m person for zero.
