VOLTAGE NONLINEAR RESISTOR COMPOSITION, AND VARISTOR AND LAMINATE VARISTOR THAT USE THE SAME
PROBLEM TO BE SOLVED: To provide a voltage nonlinear resistor composition that develops voltage nonlinearity even when an unbaked variator material and a less noble metal electrode having low resistance are burned integrally with each other, and enables the same level dense sintering as a case where they are burned in atmosphere.SOLUTION: A voltage nonlinearity resistor composition contains Zn element, Co element, Si element and at least one kind of element or element group selected from the group consisting of Sr element, Ca element and Ba element. When the at least one kind of element or element group selected from the group consisting of the Sr element, the Ca element and the Ba element is represented by A, and with respect to the mole ratios of the Zn element, the Co element, the Si element and A, the mole ratio of Zn is represented by (1-x), the mole ratio of Co and Al is represented by x and the mole ratio of Si is represented by y, x and y are located on lines or a range surrounded by the points a(0.0025, 0.0025), b(0.0025, 0.025) and c(0.025, 0.025) on the x-y flat plane coordinate (x,y).SELECTED DRAWING: Figure 1
【課題】未焼成のバリスタ材料と低抵抗の卑金属電極とを一体焼成しても、電圧非直線性を発現し、大気中で焼成した場合と同等レベルの緻密焼結化が可能な電圧非直線性抵抗体組成物を提供する。【解決手段】Ｚｎ元素と、Ｃｏ元素と、Ｓｉ元素と、Ｓｒ元素、Ｃａ元素およびＢａ元素の少なくとも一種から選ばれる元素もしくは元素群とを含み、これらＳｒ元素、Ｃａ元素およびＢａ元素の少なくとも一種から選ばれる元素もしくは元素群をＡとしたときＺｎ元素、Ｃｏ元素、Ｓｉ元素およびＡのモル比においてＺｎのモル比を（１−ｘ）、ＣｏとＡのモル比をそれぞれｘ、Ｓｉのモル比をｙとしたときｘとｙはｘ−ｙ平面座標（ｘ、ｙ）において以下の点ａ（０．００２５、０．００２５）、ｂ（０．００２５、０．０２５）、ｃ（０．０２５、０．０２５）の点で囲まれる線上または範囲内を満たす電圧非直線性抵抗体組成物。【選択図】図１
