Abstract

According to the relative density change models of sintered ceramic material and grain variation model

sintering temperature and holding time of Al2O3ceramics were identified

and sintering process was presented to determine the optimized parameters.Maximum sintering temperature and holding time are the important factors affecting the performance of sintered composites.The results show that with Al2 O3 +0.2%MgO+0.4%SiO2

molding pressure of 200MPa

and heating from 550℃to 1 000℃for 12min

and then from 1 000℃to maximum sintering temperature with heating rate of 2℃/min as well as at holding temperature 1 600℃for 2hours

ceramic filar guide exhibits desirable microstructure with excellent mechanical properties.
