The (Mn,Ni)3O4 oxide ceramic body has spinel structure. Its resistance will drop rapidly as temperature rises; this characteristic is applied to NTC (Negative Temperature Coefficience) thermal sensitive thermistor device. The (Mn,Ni)3O4 NTC material belongs to the high value resistance of thermistor, that is limited on the range of application of industry. Therefore, industries make efforts in developing low value resistance NTC to increase its application. The way of industries use is add Cu and replace some Ni to the main material, (Mn,Ni)3O4, in order to get the result of reducing the value of resistance. Learned by documents though Cu is it can reduce the value of resistance, the problem is its stability become poor under the high-temperature environment. This experiment is adopted and joined with (Mn,Ni,Cu)3O4 is all 8YSZ ( 8mol% Y2O3 and 92mol% ZrO2) the same of cubic phase, to make the solid solution of 8YSZ dissolve into (Mn,Ni,Cu)3O4; and then change its crystal structure and increase its stability used under high-temperature environment. The experimental result leads to the conclusion that acts as the adding amount of 3% and 1% 8YSZ really make the problem of adding Cu to (Mn,Ni)3O4 is being improved obviously.
