Performance of Al₂O₃ Ceramics with Different Thermal Histories

Abstract:

The mechanic properties mainly the room temperature bending strength and the creep of the Al₂O₃ ceramic specimens which were prepared by cold isostatic pressing and had undergone different thermal histories have been measured and compared. The results suggest that the bending strength of the ceramic increases after high temperature soaking. The ceramic can withstand cyclic rapid cooling with an initial temperature of 200 °C. The sample has shown a very good dimensional stability after a long service time (50h) at 1550 °C.
