Abstract (en)
[origin: US4536328A] A composition for making electrical resistance elements including a conductive component which comprises (a) a precious metal oxide of the formula 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; B'' is one or more of Ti, Cd, Zr, V and Co, O<x<0.2; O<y<0.2; (b) a binder component which comprises (i) between 40 weight percent and 75 weight percent C', wherein C' is SrO when A' is Sr, C' is BaO when A' is Ba, and C' is SrO+BaO when A' is Sr and A'' is Ba and when A' is Ba and A'' is Sr, (ii) between 20 weight percent and 35 weight percent B2O3, (iii) between 2 weight percent and 12 weight percent SiO2, and (iv) between 0.5 weight percent and 6.5 weight percent ZnO. The method of the present invention includes mixing the conductive component and binder as described above with an organic vehicle.
