The secondary pressure assisted flash sintering process of tetragonal zirconia ceramics was developed. The process optimized the process and eliminated the deterioration of microstructure caused by high power flash sintering at critical flash temperature. The results show that: the multi-step pressure assisted flash sintering process retains the advantages of low-temperature and instantaneous sintering, avoids the complex green pressing process and the high cost of precious metal electrode. Yttrium stabilized zirconia can be densified by multiple flash sintering. The sintering temperature is lower than 1 050℃ and the sintering time is less than 200 s. The density of tetragonal zirconia ceramic material prepared by this process is more than 90%.
