The several kinds of Ag-NiFe2O4 cermets with different mass percent of Ag have prepared. Microstructural changes were observed by scanning electronic microscope and composition was determined with x-ray detector. Effect of different content of Ag on the density, property of thermal shock,conductivity and corrodent rate were tested. The results showed that the thermal shock performance and conductivity have improved in company with the addition of content of Ag.

制备了不同金属Ag含量的Ag-NiFe2O4金属陶瓷，利用扫描电子显微镜观察显微组织，由X射线衍射分析化学成分，研究了Ag的添加量对其体积密度、气孔率、热震性、导电率以及腐蚀速率的影响，试验结果表明，抗热震性和导电能力随着Ag含量的增加而增强，导电率的提高和腐蚀率的增大仍是一对突出的矛盾。
