Summary:Title screen
This work explores compaction of fine ZrO2 powders doped with Y2O3 and MgO. ZrO2(MexOy) powders are obtained by plasma chemical synthesis and chemical precipitation from salt solutions. Powder compaction is studied during the nonisothermal sintering process. It is shown that the ZrO2(Y2O3) powder synthesized by chemical precipitation demonstrates the lowest degree of compaction during sintering. With the same synthesis method and similar size distribution of ZrO2(MexOy) powders, the difference in the compaction kinetics is determined by the different number of oxygen vacancies. The higher number of oxygen vacancies in the ZrO2(MgO) powder obtained by plasma chemical synthesis, provides the highest compaction rate compared to the ZrO2(Y2O3) powder. According to mercury porosimetry, ZrO2(Y2O3) powders of the same composition obtained by plasma chemical synthesis and chemical precipitation, have very different porosity. The highest compaction rate for all compacts is observed at the heating stage. After sintering, ZrO2(Y2O3) ceramic samples show similar values of compaction rate. Research findings may be useful to specialists involved in the development and synthesis of fine ceramic powders
