  • Current/voltage non-linear resistor and sintered body therefor
    Patent number: 6627100
    Abstract: A current/voltage non-linear resistor comprises a sintered body having a main component of ZnO, an electrode applied to a surface of the sintered body and an insulation material applied to another surface of the sintered body. The main component containing, as auxiliary components, Bi, Co, Mn, Sb, Ni and Al, and the contents of the auxiliary components are respectively expressed as Bi2O3, Co2O3, MnO, Sb2O3, NiO and Al3+, of Bi2O3: 0.3 to 2 mol %, Co2O3: 0.3 to 1.5 mol %, MnO: 0.4 to 6 mol %, Sb2O3: 0.8 to 7 mol %, NiO: 0.5 to 5 mol % and Al3+: 0.001 to 0.02 mol %; a Bi2O3 crystalline phase in the sintered body including an &agr;-Bi2O3 phase representing at least 80% of the total Bi2O3 phase.
