We investigate the reactive flash sintering of Mg0.2Ni0.2Co0.2Cu0.2Zn0.2O precursor powders prepared by a polymeric synthesis route. The flash experiments were performed at a constant heating rate of 10 °C min−1 with electric fields from 15 to 60 V cm−1. The single-phase rock-salt structure was obtained in just a few seconds at furnace temperatures as low as 500 °C, under an electric field of 60 V cm−1 and a current density of 150 mA mm−2. Success at processing an entropy-driven phase in a remarkably short time and low furnace temperature demonstrates the potential of reactive flash sintering for producing entropy-stabilized materials.

熵稳定氧化物Mg0.2Ni0.2Co0.2Cu0.2Zn0.2O的反应闪蒸

我们研究了通过聚合合成路线制备的 Mg0.2Ni0.2Co0.2Cu0.2Zn0.2O 前驱体粉末的反应性闪光烧结。闪光实验在 10 °C min-1 的恒定加热速率下进行，电场为 15 至 60 V cm-1。在低至 500 °C 的炉温、60 V cm-1 的电场和 150 mA mm-2 的电流密度下，仅几秒钟即可获得单相岩盐结构。在极短的时间内和低炉温处理熵驱动相的成功证明了反应快速烧结生产熵稳定材料的潜力。
