A novel synthesis route to obtain transparent multifunctional ceramics by using SPS has been proposed. Transparent lutetium niobate (Lu3NbO7) had a cubic defect-fluorite structure, where Lu and Nb cations randomly occupy the 4a site, and 1/8 of the 8c site for O anion is statistically defective. Such disordering of cations and O defects makes Lu3NbO7 is an interesting multifunctional material. Transparent Lu3NbO7 ceramics had a uniform microstructure and the transmittance at 550 nm reached at 68%. TEM observation suggests the formation of ordered structure in Lu3NbO7 ceramics.

提出了一种利用SPS合成透明多功能陶瓷的新途径。透明NbO7具有立方缺陷-萤石结构，其中Lu和Nb离子随机占据4a位，而O阴离子8c位的1/8是统计缺陷。这种阳离子和O缺陷的无序性使Lu3NbO7成为一种有趣的多功能材料。透明的Lu3NbO7陶瓷具有均匀的显微结构，在550 nm处的透过率达到68%。透射电子显微镜观察表明，在Lu3NbO7陶瓷中形成了有序结构。
