摘 要：<正>The automatic crystallization of MgO duringthe sintering of Si3N4-MgO-CeO2 is first discovered.ForSi3N4-MgO-CeO2,ceramics,the MgO-CeO2 would reactwith SiO2 to form liquid at 1450℃ and then transform intoglassy phase in the sintered bodies after cooling down.Above1550℃,MgO would crystallize automatically during sinter-ing.So the glassy phase which is harmful to the high temper-ature properties is then eliminated.The present work is ofgreat value for theoretical study and application.
