采用反应辅助快速烧结法在室温下成功地合成了五元熵稳定氧化物陶瓷（Mg0.2Ni0.2Co0.2Cu0.2Zn0.2O）。与传统的烧结技术相比，起始材料在短短几秒钟内就完全转化为单一的岩盐相。分析表明，电场显著加快了相变速率。这些结果清楚地表明，采用反应辅助快速烧结技术来制造具有新的化学性质和有吸引力的性能的熵稳定的氧化物的可行性。
Five-component entropy-stabilized oxide ceramic (Mg0.2Ni0.2Co0.2Cu0.2Zn0.2O) has been successfully synthesized by reaction assisted flash sintering at room temperature. Compared to the conventional sintering technique, the starting materials have been completely transformed to a single rocksalt phase in just a few seconds. Analysis suggests that the electric field significantly accelerated the rate of phase transition. These results clearly demonstrate the feasibility of employing the reaction assisted flash sintering technique to fabricate entropy-stabilized oxides with new chemistries and attractive properties.
