研究并分析了 Ni3+ 掺杂和 Co2 + 掺杂对 Sn O2 压敏电阻致密度和电学非线性性能的影响。研究了掺Mn2 +对 Sn O2 · Ni2 O3· Nb2 O5压敏材料性能的影响。发现 x(Mn CO3)为 0 .10 %时 ,压敏电阻具有最高的视在电场(EB=6 86 .89V/ m m)和最好的电学非线性性能 (α=12 .9)。样品的收缩率和致密度变化趋势不一致 ,这是因为样品的致密度是由收缩率和 Mn CO3的挥发量两因素共同决定的
The effects of Ni3 + doping and Co2 + doping on the density and electrical nonlinearity of SnO2 varistor were investigated and analyzed. The effects of Mn2 + on the properties of Sn O2 · Ni2 O3 · Nb2 O5 pressure-sensitive materials were investigated. The varistor has the highest apparent electric field (EB = 866.89V / m m) and the best electrical nonlinearity (α = 12.9) when x (Mn CO3) is found to be 0.10%. Sample shrinkage and density trends inconsistent, this is because the density of the sample is determined by the shrinkage rate and Mn CO3 volatile amount of two factors together
