发明名称 CERAMIC COMPOSITION OF VOLTAGE NON-LINEAR VARIABLE RESISTANCE, ELECTRONIC COMPONENT, AND MULTILAYER CHIP VARISTOR
摘要 <P>PROBLEM TO BE SOLVED: To provide a ceramic composition whose resistance varies non-linearly depending on the applied voltage which can be sintered sufficiently and can be reduced in electrostatic capacity, even if the circuit voltage is lowered and has superior lifetime characteristics with respect to high voltage load, and to provide an electronic component, such as a multilayer chip varistor which uses the composition. <P>SOLUTION: The ceramic composition, whose resistance varies non-linearly depending on the applied voltage, consists of a main component containing a zinc oxide, a first subcomponent containing an oxide of a rare earth element, a second subcomponent containing an Sb oxide, and a third subcomponent containing at least one kind of either the oxide of Cr or Mo. The ratio of the third subcomponent to 100 mol of the main component is 0.001 atomic %<third subcomponent<2 atomic %, in terms of Cr and Mo. <P>COPYRIGHT: (C)2005,JPO&NCIPI
