Abstract

Compaction of specimens consisting of 70% Al2O3 and 30% of ZrO2(2Y2O3) has been studied during UHF sintering and furnace heating (FH). Kinetics of the change in density and pore size distribution at 1500 and 1600°C have been studied. The compaction rate is higher with UHF heating than with FH over the whole range of temperature and exposure time. Retention of small pores with UHF heating for a long time supports the high level of capillary forces and promotes ceramic material compaction.
