在鎳銅鋅鐵氧磁體中添加變阻形成劑氧化鉍可做出具有變阻性質之電感-變阻器之複合材料，由於聚集在晶界的二次相會提高試片之變阻性質，故藉由改變試片燒結之降溫速率與多增加一段熱處理讓位於晶界附近之二次相增多進而提升變阻性質。
在改變燒結之降溫速率時發現，鉍有擴散現象且多經一段熱處理後會使擴散現象加劇，擴散的鉍與其他元素反應形成二次相聚集在晶界，此富鉍二次相的厚度為影響變阻性質之主因。
Zn0.5Ni0.3Cu0.19Nb0.01Fe2.1O4 +δ + 5wt%Bi2O3以950℃燒結2小時爐冷到室溫，再經650℃熱處理1小時可得到非線性係數10.8與在頻率10MHz初導磁係數約225之變阻器-電感之多功能材料。

A low temperature-fired multifunctional varistor-magnetic ferrite materials can be obtained by adding Bi2O3 into NiCuZn ferrites. The varistor property can be promoted by choosing a proper cooling rate and adding a thermal annealing process after sintering to result in the bismuth diffusion and the precipitation of the Bi-rich second phase near the grain boundary.
The multifunctional varistor-magnetic ferrite material with a nonlinear coefficient, α, of 10.8 and initial permeability of 225 was obtained for the Zn0.5Ni0.3Cu0.19Nb0.01Fe2.1O4 +δ + 5wt%Bi2O3 sintering at 950oC for 2 h, furnace cooling to room temperature and then annealing at 650oC for 1 h.
