| 摘 要： | 部分稳定氧化锆(PSZ)质泡沫陶瓷过滤器是用于高温合金及铸钢金属液净化的一种性能最为理想的过滤材料。以Mg-PSZ为骨料,CeO2、富铈稀土为添加剂制备的泡沫陶瓷过滤器具有较好的高温性能。在利用扫描电镜、X衍射仪对泡沫陶瓷过滤器晶相及组织形貌进行分析的基础上,文章就部分稳定氧化锆中稳定相对高温性能的影响进行了较深入的探讨。

| Abstract: | Ceramic foam filter(CFF) made from partially stabilized zirconia(PSZ) is a kind of ideal filter material used to purify melted casting steel and high temperature alloys for improving quality of the cast.The ceramic foam filter that is made from Mg-PSZ powder with the additions of CeO2 or the rare earth abounding with CeO2 has excellent high temperature performance.In this paper,the effect of the stability phase in PSZ on the high temperature performance is deeply discussed,on the base of the CFF's crystal phase constitution and morphology analysis by means of modern analytic methods such as SEM and XRD spectra. |
