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.
