具有较高品质因数的热电氧化物具有层状结构。由于它们具有热电各向异性，为了实现最佳性能，应制备织构晶轴取向的陶瓷。我们已经成功地制备了钇取代的（ZnO）5In 2 O3的反应模板晶粒生长（RTGG）技术织构陶瓷，并取得了最高的优值（ZT <$0.33在1073 K）的n型氧化物材料迄今为止报道。
Thermoelectric oxides with comparatively high figures of merit possess layered structures. Because they exhibit thermoelectric anisotropy, textured crystal-axis-oriented ceramics should be produced in order to realize the best performance. We have succeeded in fabricating textured ceramics of yttrium-substituted (ZnO)5In2O3 by the reactive templated grain growth (RTGG) technique, and achieved the highest figure of merit (ZT∼0.33 at 1073 K) among n-type oxide materials reported so far.
