摘要
采用两种不同的工艺过程对引入滑石的高铝瓷进行烧结，比较其制品性能，并应用ＸＲＤ和ＳＥＭ分析晶相。结果发现，存在非平衡相α－石英的样品其力学性能优于存在平衡相莫来石的样品。这表明，可以通过烧结工艺改变陶瓷制品中的晶相，从而获得性能优良的陶瓷材料。
The high-alumina ceramics of talc addition is sintered by two technological processes, the perfomance of two samples is compared, and crystal phase is analyzed by XRD and SEM methods. Results show that mechanical property of sample containing non-equilibrium phase α-quartz surpasses the sample containing equilibrium phase mullite.It shows that ceramic material with good performance can be obtained by sintered technique to change crystal phase in ceramics product.
