摘要:
A method of manufacturing a voltage nonlinear resistance element comprising the steps of providing a mixture of main component ZnO and auxiliary components of at least a rare earth element, Co and B in a mold, placing the mold in a sheath box having openings in the surfaces thereof, and baking the mold in the sheath box. The preferred ratio of the area of the openings in the sheath box to the total surface area of the sheath box is 10-90% to produce the voltage nonlinear resistance elements having favorable long wave tail surge withstanding data and an acceptable ratio of a voltage developed across the terminals of the element when a current of 1 mA flows in the element.
