| description | (Mg, Co, Ni, Cu, Zn)<sub>1−x</sub>Li<sub>x</sub>O is a type of high-entropy oxide that has high ionic conductivity at room temperature and is used as a solid electrolyte. (Mg, Co, Ni, Cu, Zn)<sub>1−x</sub>Li<sub>x</sub>O was successfully synthesized from precursor powder by applying reactive flash sintering for less than 4 min at room temperature (25 °C). AC and DC electric fields were independently applied to sinter ceramic samples; consequently, AC and DC electric field application resulted in relative densities that exceeded 90% and 80%, respectively. X-ray diffraction spectra of samples revealed the existence of a clear halite structure with an insignificant impurity phase, proving that (Mg, Co, Ni, Cu, Zn)<sub>1−x</sub>Li<sub>x</sub>O crystals were successfully produced. |
