Embodiment 1
[0020] A preparation method of varistor edge coating slurry is carried out according to the following steps:
[0021] 1. First, accurately weigh 3.0572 grams of ZnO and 32.8428 grams of Sb with a purity of ≥99% 2 o 3 , 37.7361 g Y 2 o 3 , 26.2478 grams Bi 2 o 3 , 0.1161 g H 3 BO 3 Put it into a ball mill jar, add 400 grams of zirconium balls and 200 grams of deionized water, and mix it with a planetary ball mill for 4 hours at a speed of 100 rpm, then quickly dry it in an oven at 140°C until it is completely dried;
[0022] 2. Crush the dried powder in step 1, put it into an alumina crucible, then put the crucible into a muffle furnace, pre-fire it at 850°C, keep it warm for 1 hour, and raise the temperature at 5°C / min, then Furnace cooling;
[0023] 3. Grind the pre-fired powder in step 2, put it into an agate ball mill jar, add 400 grams of zirconium balls and 250 ml of ethanol, mix it with a planetary ball mill for 4 hours at a speed of 100 rpm, and then bake it in ...
