High field varistors (1020) were fabricated in the system ZnO-CoO-PbO-Bi/sub 2/O/sub 3/ by hot pressing and by pressureless-sintering techniques. These varistor compositions are particularly suitable for applications at high current densities (J>1 A/cm/sup 2/) where the nonlinearity coefficients reach maximum values. Variations in electrical properties with processing and composition are described.
