Process for the preparation of voltage non-linearity type resistors.

摘要

A process for preparing voltage non-linearity type resistors comprises pre-sintering a basic composition comprising X mole % of ZnO and (100 - X) mole % of Fe2O3 (wherein 40 </= X </= 60), at a temperature no lower than 700 DEG C, adding to the pre-sintered material 0.01 - 40% by weight of at least one of V2O5, Bi2O3, MgO, Al2O3, MoO3, Sb2O3, SiO2, NiO, SrO2 or PbO, and sintering the resulting mixture.
