摘要： Cermet resistors based on ruthenium dioxide and in some instances iridium dioxide have been found to have unusually low Temperature Coefficients of Resistivity (TCR) when a particular glass frit and a vanadium oxide additive are utilized. These unique resistors exhibit TCR's of less than .+-.25 ppm/.degree. C over -55.degree. to .+-.150.degree. C with the extremes of the TCR varying less than 20 ppm. The vanadium, iridium and ruthenium oxides can be used as such or derived from metal resinates.

摘要： ELECTRICAL RESISTORS CAN BE MADE BY APPLYING TO CERAMIC DIELECTRIC SUBSTRATE, AND FIRING, A COMPOSITION OF A RHOMBOHEDRAL PLATINUM COBALT OXIDE HAVING THE SPACE GROUP R3M. USUALLY, THE OXIDE HAS THE FORMULA PTXCOYO2, IN WHICH EACH OF X AND Y IS ABOUT 0.85 + 0.15, BUT IT ALSO CAN CONTAIN ABOUT 0.1-2.0% BY WEIGHT OF MANGANESE IN ITS CRYSTAL LATTICE. IN THE LATTER CASE, THE OXIDE HAS THE FORMULA PTXMNZCOYO2, IN WHICH X AND Y ARE AS ABOVE, AND Z IS A VALUE FROM 0.004 TO 0.11.

摘要： THE FIELD OF CERMET RESISTORS IS REVIEWED, PROBLEMS ASSOCIATED THEREWITH ARE DISCUSSED, AND THE EFFORTS OF CERTAIN PRIOR WORKERS ARE SUMMARIZED. AN IMPROVED RESISTANCE COMPOSITION IS DESCRIBED EMPLOYING, AS THE CONDUCTIVE FRACTION, A MIXTURE OF GOLD, SILVER OR PLATINUM WITH THE OXIDE OF IRIDIUM OR RUTHENIUM. RESISTORS ARE PRODUCED HAVING EXCELLENT NOISE, TCR AND OTHER PROPERTIES AT RESISTANCES OF UP TO 10 MEGOHMS PER SQUARE, AND IN NO INSTANCE IS FRIT CONTENT HIGHER THAN ABOUT 78%. THE METHOD OF PRODUCING THESE RESISTORS IN A READILY REPRODUCIBLE MANNER IS DETAILED, AND THEIR PROPERTIES ARE ILLUSTRATED.
