| 简介 |
A method for manufacturing a current-voltage non-linear resistor is a method in which a mixture containing zinc oxide as a main component raw material and also containing at least bismuth oxide, antimony oxide, manganese oxide, cobalt oxide, nickel oxide, a rare earth element R, boron and silver as auxiliary component raw materials is fired. The relative ratio of the average particle diameter (D50s) of the auxiliary component raw materials to the average particle diameter (D50z) of zinc oxide in the mixture is equal to or less than 0.60 (D50s/D50z ≤ 0.60). The average particle diameter (D50z) of zinc oxide is 700 nm or less. The mixture contains boron in an amount of 0.005 to 0.04wt% in terms of B2O3 content, and contains silver in an amount of 0.005 to 0.04wt% in terms of Ag2O content. The relative ratio of the content of boron to the content of silver satisfies the relationship represented by the formula : 0.125 ≤ B2O3/Ag2O ≤ 1.00. |
