Mn_(1.05-x)Co_(0.92)Ni_(0.03)SiO_4 (0≤x≤0.05) series NTC thermistor samples were prepared using the conventional ceramic technique. The effects of Si-doping amount on the phase structure and electric properties of the samples were studied using XRD, SEM and electric property measurements. The results show.that in the range of 0≤x≤0.03, the spinel cubic phase and tetragonal phase co-existed as solid solution in the samples, and the resistivity at room temperature P25 and B_(25/50) value of the sample increased with increasing Si-doping amount. When 0.03<x≤<0.05, the tetragonal phase was absence and only spinel cubic phase existed in the samples, and the B25/50 value and P25 of the sample decreased with increasing Si-doping amount. The obtained sample with x = 0.03 sintered at 1 373 K show optimal electric properties with P25 of 79 501 Ω · cm and B_(25/50) value of 4 142 K |
