A series of Nd and Ce co-doped Gd_2-xNd_xZr_2-yCe_yO₇ (0.0 ≤ x, y ≤ 2.0) ceramics were rapidly fabricated through spark plasma sintering (SPS) within 3 min. The effects of Nd and Ce contents on the phase composition, lattice parameter, active modes, microtopography and microstructure have been investigated in detail. XRD studies reveal that the compositions corresponding to 0.0 ≤ y ≤ 1.0 show a single phase and beyond 1.0 exhibit multiphase. The lattice parameters increase with elevated Nd and Ce content. The grains are densely packed on each other with cube-like shape, and the elements are almost homogeneously distributed in the compound. This synthetic method provides a simple pathway for the preparation of highly densified single phase ceramic at 1600–1700 ℃ for 3 min under pressure of 80 MPa.

一系列的Nd和Ce共掺杂的Gd _{2- X}钕_X的Zr _{2- ý}铈_Ý ø ₇（0.0 ≤X ，ÿ≤ 2.0）陶瓷迅速通过火花等离子体制造在3分钟内烧结（SPS）。详细研究了Nd和Ce含量对相组成，晶格参数，活性模式，微观形貌和微观结构的影响。XRD研究表明，对应于0.0的组合物中≤ÿ≤1.0表示单相，超过1.0表示多相。晶格参数随Nd和Ce含量的增加而增加。颗粒彼此密集地堆积成立方体状，并且元素几乎均匀地分布在混合物中。这种合成方法为在80MPa压力下在1600-1700℃下制备3分钟的高密度单相陶瓷提供了一条简单的途径。
