This powder was pressed into a disk having a diameter of 50 m and a thickness of 30 m. After firing at 500'C in air to remove the added dispersant, binder, and lubricant, a pre-prepared slurry for forming a high-resistance layer was applied to the calcined body at 1020°C using a spray gun. .

ＺｎＯ。Although the direct cause of the stable life characteristics of the embodiments of the present invention is not clear, the following can be roughly considered. It has been known from past research that addition of a component that forms a glass phase is effective in improving or stabilizing the life characteristics in most composition systems of nonlinear resistors containing ZnO as a main component. However, as shown in the conventional example, there are various problems such as deterioration or large variation in life characteristics, and the reality is that there is no one that can satisfy the life characteristics. The main reason for this is thought to be that the components forming the glass phase, which have an effect on the life characteristics, are required in very small amounts, at most 1000 PPH or less in total. In other words, a major factor is that it is difficult to sufficiently uniformly disperse components forming a very finely divided glass phase with other components in the mixing process. Therefore, an element with relatively good dispersion must have good lifetime characteristics, but
Elements in areas with poor dispersion will also have poor life characteristics. The present invention takes aim at this dispersibility problem and uses ZnO from the beginning.
Ｂ２Ｏ３、ＡＣ＋２０のみを十分混合、均一なＺｎＯと
８２０３ 、 Ａ（７２Ｑの混合物を得た後、他の添加
物を混合する方法により微量のガラス相を形成する成分
の分散性が良くなり寿命特性が安定したものでおろう。After sufficiently mixing only B2O3 and AC+20 to obtain a uniform mixture of ZnO, 8203, and A(72Q), the method of mixing other additives improves the dispersibility of the components that form a small amount of glass phase and improves the life characteristics. I hope it's stable.
なおガラス相成分の添加囚を単純に増やしても非直線特
性が悪化するのみでか命特性も改善されず得策ではない
。It should be noted that simply increasing the amount of glass phase component added will only worsen the nonlinear characteristics and will not improve the life characteristics, which is not a good idea.
