摘要：
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.
