【Abstract】 The sintering process and the mechanism of zircom porous ceramics prepared with industrial zirconnia,natural quartz and a small amount o dopant of fluoride have been investigated,The test results have shown that in the tempertuer range of the study,the atom diffusion of the system is completed by gas phase,and the reactive sintering process is accompanied by the existence of gas phase,The synthetic reaction of zircon amd the sintering process take place in turn.更多还原
