摘要
本文对典型成分刚玉质泡沫陶瓷过滤网进行了烧结温度和保温时间试验,并通过对其显微组织、岩相构成以及高低温力学性能进行观察分析,得出:刚玉质泡沫陶瓷过滤网的泰漫温度约为1400℃,在1500℃～1600℃保温2～4小时烧结时,烧结和固相反应完全,晶相构成了理想的空间骨架,其高低温性能和热稳定性均较好,并能满足生产应用.
The ceramic foam filters composed of about 80 wt% aluminum oxide have been produced. The effect of sintering temperature and holding time on microstructure and mechanical properties have been studied. The physical and mechanical properties as well as its' thermal expansion under static load of the filter have been tested. The analyses of the relation between the microsturcture, properties and sintering processes, showed that the Tamman Temperature of the filters is abour at 1400℃, and when the filters were sintered for 2~4 hours at 1500~ 1600℃, solid-state reactions and sintering were almost copleted, the properties at high and room temperature, and the stability at high temperature were fair reasonable.
