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 Fe 2 O 3 (wherein 40 ≦ X ≦ 60), at a temperature no lower than 700°C, adding to the pre-sintered material 0.01 - 40% by weight of at least one of V 2 O 5 , Bi 2 O 3 , MgO, Al 2 O 3 , MoO 3 , Sb 2 0 3 , SiOz, NiO, SrO 2 or PbO, and sintering the resulting mixture.
