A study of the compaction of zinc oxide powder under conditions simulating the process of cold sintering described in the work of the research group of K. Randall carried out in 2017 in the USA is presented. The results obtained show that dense zinc oxide ceramics can be obtained by pressing (pressing pressure p = 77 MPa) in an aqueous medium at temperatures of 220-250 ° C. It was found that during pressing under the indicated conditions, two processes occur - compaction and grain growth, which are characteristic of sintering. The reproducibility of the cold sintering process is shown. The urgency of further research in this area has been substantiated.
