Abstract
This invention belongs to the technical field of resistive electrical components, and specifically relates to a method for preparing a zinc oxide resistor with high gradient and high current flow stability. The zinc oxide resistor comprises: zinc monoxide, bismuth trioxide, antimony trioxide, nickel trioxide, manganese tetroxide, cobalt tetroxide, tin dioxide, boron trioxide, nano-silver powder, aluminum nitrate nonahydrate, barium acetate, binder, dispersant, and deionized water. The zinc oxide resistor designed in this invention has the advantage of good stability under high gradient and high current flow, overcoming the degradation behavior of existing zinc oxide varistors caused by the influence of high current surge impact on the zinc monoxide grain boundary barrier, and is suitable for industrial application.
