The donor impurity and grain boundary combustion-supporting agent containing acceptor impurity were added successively in the ceramic powder during ceramic powder preparation, both of them can also promote grain growing and semiconductive, and the combustion-supporting agent can be good to form insulation layer in oxidizing process.
采用一次性烧成技术研制了晶界层半导体陶瓷电容器,在瓷料配制过程中先后加入施主杂质和含有受主杂质的晶界助烧剂,两者在还原烧成时促使晶粒生长并半导化,助烧剂在氧化时有利于晶界绝缘层形成。

In the research of prescription, through the experiments we knew the influence from the Nb_2O_5 or Y_2O_3 single donor doped on high-temperature PTC ceramic, and got the curve graph drawing the resistivity and mixing quantity. In order to restrain lead volatilize and mix the rang of donors to neutralization the harmful acceptor impurity in raw materials, adopt the prescription design of Nb_2O_5 and Y_2O_3 double donors-doped. From the result, we know that regulation proportion of Nb , Y double donors, can make high-temperature PTC ceramics semiconducting, the pottery demonstrates good electric performance.
为了能够更有效的抑制铅挥发,并且使掺杂范围能够更好的调节,以"中和"原材料中的有害受主杂质,在配方设计中采用了Nb_2O_5和Y_2O_3双施主掺杂的配方,由结果可知,适当的调节Nb、Y双施主掺杂总量及Nb、Y掺杂比例,可以使高温PTC陶瓷充分的半导化,陶瓷表现出良好的电性能。
