【摘要】 本文研究了ZrO₂-MgO系湿敏陶瓷Zr/Mg比及添加剂对其湿阻性能的影响,摸索了有关配方和工艺。实验结果表明,提高Zr/Mg比,并引入某些M₂O₃（M为三价金属元素）外加剂对湿阻性能有利,但低温下元件的阻值仍较高。进一步添加外加剂如Li₂CO₃,可使湿阻性能得到改善。更多还原

【Abstract】 The effects of Zr/Mg ratio and additives on the humidity-resistance characteristics of the ZrO₂-MgO ceramics were studied. The batch compositions and the manufacturing technique were explored. The results showed that by increasing the Zr/Mg ratio and also by introducing some additives such as M₂O₃ （M-trivalent metal element）, the humidity-resistance characteristics were improved. But in the case of lower humidity, the resistance of humidity remains high. The humidity-resistance characteristics can be improved further by introducing some additives such as Li₂CO₃更多还原
