Abstract (en)
[origin: US4814107A] A nitrogen fireable resistor composition comprising: a. a conductive phase containing (1) a perovskite of the form A'1-xA''xB'1-yB''yO3, wherein when A' is Sr; A'' is one or more of Ba, La, Y, Ca and Na, and when A' is Ba, A'' is one or more of Sr, La, Y, Ca and Na, B' is Ru and B'' is one or more of Ti, Cd, Zr, V and Co, O<x<0.2; 0<y<0.2, (2) 5 to 30 weight % of a metallic copper powder, nickel metallic powder or cupric oxide, relative to the total conductive phase weight, and b. a glass phase selected from the group consisting of (a) 40 to 60 mole % SrO or BaO, 25 to 45 mole % B2O3, 0 to 6 mole % ZnO, 0.25 to 2.0 mole % TiO2, 2 to 14 mole % SiO2 and (b) 40 to 60 mole % SrO or BaO, 25 to 45 mole % B2O3, 5 to 20 mole % Al2O3, 0.25 to 2.0 mole % TiO2.
