Abstract
Compaction of specimens consisting of 70% Al2O3 and 30% of ZrO2(2Y(2)O (3)) has been studied during UHF sintering and furnace heating (FH). K inetics of the change in density and pore size distribution at 1500 an d 1600 degrees C have been studied. The compaction rate is higher with UHF heating than with FH over the whole range of temperature and expo sure time. Retention of small pores with UHF heating for a long time s upports the high level of capillary forces and promotes ceramic materi al compaction.
