Abstract

Abstract PURPOSE:To enable a voltage non-linear resistor porcelain to be kept high in high-energy resistance making it retain a nun-linear index by a method wherein a specific element, a specific atom% of Pb, and at least a specific atom% of an element selected from V, Ge, Nb and Ta are added to porcelain composition mainly composed of zinc oxide. CONSTITUTION:Af least an element selected out of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, Co, at least an element selected from B, Al, Ga and In, 0.002 to 2 atom% of Pb, and 0.01 to 0.2 atom% of at least an element selected out of V, Ge, Nb and Ta are added to zinc oxide or a main component for the formation of a voltage non-linear resistor porcelain composition. 0.01 to 0.5 atom% of Bi is added to the porcelain composition. By this setup, a non-linear resistor porcelain of the above composition is enhanced in high energy resistance and stable in characteristics even if a large amount of energy is applied.
