Advanced Ceramics

Among the advanced rare earth ceramic materials, rare earth can be used not only as matrix component, but also as doping modification element. Rare earth ions are used as additives to adjust the internal microstructure of materials and change the macroscopic properties of materials, so as to obtain various rare earth structural ceramics and rare earth modified functional ceramics.

Rare earth ceramics have special dense structure because of its unique 4f electronic layer, high electric price, large radius, compact structure, strong polarization, high chemical activity, strong reducibility and hydrolysis ability. At the same time, the sintering, compactness, phase structure and microstructures of ceramics are improved. The mechanical, electrical, optical and thermal properties of ceramics meet the special requirements.
