摘　　要：利用Si3N4-SiC材料在冰晶石静态融盐电解质中的腐蚀实验研究材料的腐蚀性能,对腐蚀增重率进行记录分析,Si3N4的含量是影响材料腐蚀性能的重要因素,根据实验测定得出Si3N4的含量越高,Si3N4-SiC材料腐蚀程度越严重。The corrosion of Si3 N4-SiC materials in the static melting salt electrolyte cryolite was studied in this paper. By the analysis of corrosion weight gain rate, it was found that the content of Si3N4 played an important factor： the higher the content of Si3N4-SiC materials, the more serious corrosion.
