    Abstract: A voltage dependent resistor of the surface barrier type. A sintered body consisting essentially of, as a major part, zinc oxide (ZnO) and 0.05 to 10.0 mole percent of, as an additive, beryllium oxide (BeO), has electrodes in contact therewith. At least one of the electrodes is in non-ohmic contact with the body. The body can have minor amounts of further additives such as nickel oxide, titanium oxide, barium oxide, stannic oxide, aluminum oxide, lead oxide, cadmium fluoride and thallium oxide.

    Abstract: A process for making a voltage dependent resistor which has a zinc oxide sintered body which itself has voltage dependent properties. The process is made up of the steps of: (1) providing a formed body of a powder mixture having as a major part zinc oxide and additive; (2) coating on the side surfaces of the formed body a paste having as the solid ingredient composition at least one member selected from the group of a) more than 50 mole % of silicon dioxide (SiO2), and less than 50 mole % of bismuth oxide (Bi2O3), b) the same composition as that of said additive, c) more than 30 mole percent of antimony oxide (Sb2O3) and less than 70 mole percent of bismuth oxide (Bi2O3), and d) more than 50 mole percent of indium oxide (In2O3) and less than 50 mole percent of bismuth oxide (Bi2O3); (3) sintering the coated body; and (4) applying electrodes to opposite surfaces of the sintered body.

    Abstract: A NONLINEAR RESISTOR WHEREIN THE NONLINEARITY IS DUE TO THE BULK THEREOF AND WHICH HAS A HIGH N-VALUE COMPRISES A SINTERED BODY OF A COMPOSITION COMPRISING ZNO AND 0.05 TO 10.0 MOLE OF BI2O3. SUCH A NONLINEAR RESISTOR HAS NONOHMIC RESISTANCE DUE TO THE BULK ITSELF, AND THE C-VALUE CAN BE CHANGED WITHOUT IMPAIRING THE NVALUE. OHMIC ELECTRODES ARE APPLIED TO OPPOSITE SURFACES OF THE SINTERED BODY. THE PRESENCE OF OTHER SPECIFIED OXIDES TENDS TO RAISE THE N-VALUE.
