Abstract (en)
[origin: EP0357113A2] A method for manufacturing a voltage-dependent, non-linear resistor having a ceramic sinter body on the basis of the oxides of titanium, bismuth and zinc oxide containing at least one transition metal as resistor material, the sinter body being manufactured by shaping the powdery resistor material and subsequently sintering in air at a temperature in the range of 1,200 to 1,350 DEG C and subsequently being fitted with electrodes, grains being added to the powdery resistor material from resistor material of a medium grain size in the range of 4 to 12 mu m prefired at a temperature in the range of 1,200 to 1,400 DEG C and in a quantity of 1 to 50% by weight. <IMAGE>
