  • Patent number: 4970027
    Abstract: A fixed chip resistor or a thick-film electrical resistor providing in circuit boards and the like and, to an electrical resistor obtained by sintering in a non-oxidizing atmosphere, resistance pastes for producing an electrical resistor and a method for making such resistors. The aforesaid objects are achieved by the provision of an electrical resistor obtained using at least one molybdate belonging to the following groups (A) and (G) with or without a fluoride of an alkaline earth metal, and an electrical resistor paste obtained using the aforesaid components with or without a carbonate of an alkaline earth metals,(A) Molybdates of alkaline earth metals,(B) Molybdate of zinc,(C) Molybdate of elements Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, and complex molybdates of two or more of said elements,(D) Molybdate of aluminum(E) Molybdates of elements zirconium and hafnium, and complex molybdates thereof, and(G) Molybdates of manganese.
