PRODUCTION OF THERMAL SHOCK RESISTANT CERAMICS

摘要

PURPOSE:To obtain ceramics having high bending strength and excellent thermal shock resistance by making the internal pressure of a furnace lower than that of closed pores formed by heating in a green temporarily for ceramics when the compact of starting materials for ceramics is sintered by hot isostatic pressing in the furnace. CONSTITUTION:When a compact of starting material for ceramics such as alumina or zirconia is put in a furnace and sintered by hot isostatic pressing, the internal pressure of the furnace is made lower than that of closed pores formed by heating in the compact.
