VOLTAGE NON-LINEAR RESISTOR & METHOD OF PRODUCING THE SAME |
摘要 |
An excellent voltage non-linear resistor is disclosed having superior lightning discharge current withstanding capability, switching surge current withstanding capability, and voltage non-linear index alpha , including a resistor element body consisting essentially of zinc oxide, and a highly resistive side layer composed of a zinc silicate phase consisting essentially of Zn2SiO4 and a spinel phase consisting essentially of Zn7Sb2O12 arranged on a side surface of the resistor element body. The porosity of the resistor element body is 2% or less. Zinc silicate particles are existing continuously in the highly resistive side layer with a porosity of 10% or less in a region of the highly resistive side layer within 30 mu m or less from the resistor element body. A method of producing the voltage non-linear resistor is also provided. |
