Embodiment 1
[0022] Weigh 14.621g of Ni 2 o 3 and 0.379g of ZnO, so that the molar ratio is 0.95:0.05. It was wet ball milled for 20 hours. The mixture was washed and then dried at 80°C to obtain a uniformly mixed ceramic powder. Grind and sieve the powder, add 3wt% PVA binder, dry press at about 4Mpa, and sinter in air at 1250°C for 4 hours to obtain Ni 0.95 Zn 0.05 O heat sensitive ceramic material. XRD test shows that the phase is basically Ni 0.95 Zn 0.05 O solid solution. The sintering radial shrinkage rate is 15.6%, the sintering performance is good, and the ceramics are relatively dense. Performance tests show that in the temperature range of 50-300°C, the B value is 4107K, and the linearity is 0.99816; in the temperature range of 50-100°C, the linearity of the resistance-temperature curve is 0.970, and the temperature coefficient of resistance TCR is -0.013 / K. Its corresponding data such as figure 1 , figure 2 , image 3 shown.
Embodiment 2
[0024] Weigh 14.222g of Ni 2 o 3 and 0.778g of ZnO, so that the molar ratio is 0.90:0.10. It was wet ball milled for 20 hours. The mixture was washed and then dried at 80°C to obtain a uniformly mixed ceramic powder. Grind the powder, sieve, add binder, dry press at about 4Mpa, and sinter in air at 1350°C for 2 hours to obtain Ni 0.9 Zn 0.1 O heat sensitive ceramic material. XRD test shows that the phase is basically Ni 0.9 Zn 0.1 O solid solution. The sintering radial shrinkage rate is 16.0%, the particle size after sintering is about 3 μm, and the sintering performance is good. Performance tests show that in the temperature range of 50-300°C, the B value is 4677K, and the linearity is 0.99534; in the temperature range of 50-100°C, the linearity of the resistance-temperature curve is 0.984, and the temperature coefficient of resistance TCR is -0.013 / K. Such as Figure 4 , Figure 5 , Image 6 , Figure 7 shown.
Embodiment 3
[0026] Weigh 13.357g of Ni 2 o 3 And ZnO of 1.643g, make its molar ratio be 0.80:0.20. It was wet ball milled for 20 hours. The mixture was washed and then dried at a certain temperature of 80° C. to obtain uniformly mixed ceramic powder. Grind the powder, sieve, add binder, dry press molding at about 4Mpa, and sinter in air at 1450°C for 2 hours to obtain Ni 0.8 Zn 0.2 O heat sensitive ceramic material. XRD test shows that the phase is basically Ni 0.8 Zn 0.2 O solid solution. The sintering radial shrinkage rate is 16.0%, and the sintering performance is good. Performance tests show that in the temperature range of 50-300°C, the B value is 4862K, and the linearity is 0.99643; in the temperature range of 50-100°C, the linearity of the resistance-temperature curve is 0.987, and the temperature coefficient of resistance TCR is -0.014 / K. Its related data such as Figure 8 , Figure 9 , Figure 10 shown.
