摘要：本文采用ZrOCl，·8H,O、Sm,O，和Yb,O，粉体作为原材料，用化学共沉淀法制备出（Sm1-Yb,),ZrO,（x=0，0.5，1.0)粉体。粉体经搬烧后，用无压烧结工艺获得（Sm-,Yb,）,Zr,O,块体材料。通过X射线衍射(XRD)、扫描电镜(SEM)和能谱分析(EDS），对在不同热处理条件和不同腐蚀剂作用下(Sm;-,Yb,),Zr,O,块体材料的相组成和微观组织结构进行比较和分析，系统地研究了(Smi-,Yb,）,Zr,O,材料热腐蚀机理。

Abstract: In this study, (Sm,-,Yb,),Zr,O,(x =0, 0.5, 1.0) ceramic powders were prepared through chemical-coprecipitation method with Sm,O, Yb,O, and ZrOCl, · 8H,O powder as raw materials. The as-prepared powders were calcinated and then pressureless-sintered to obtain (Sm,-, Yb,),Zr,O, bulk materi-als. Its phase compositions and microstructures were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) measurements under differ-ent corrosive agents and heat treatments conditions.The hot corrosion mechanisms of(Sm,-,Yb,),Zr,O, ceramic were systematically investigated.
