    Abstract: PALLADIUM OXIDE OR OTHER METAL OXIDE REISTORS FOR MICROELECTRONIC CIRCUITRY ARE PROVIDED WITH A HIGH DEGREE OF REPRODUCIBILITY AND STABILITY BY FIRST CONCENTRATING TO POWDER FORM A LIQUID MIXTURE OF A RESISTOR METAL-ORGANO METALLIC COMPOUND, AT LEAST ONE OTHER STABLILIZER METAL IN ORGANOMETALLIC FORM, AND AN ANTI-AGGLOMERATING AGENT WHICH WILL NOT BURN OFF DURING PROCESSING TO FINAL RESISTOR FORM. THE POWDER IS THEN ALLOYED AND THE RESISTOR METAL OXIDIZED. THE RESULTING ALLOY IS THEN FORMED INTO A RESISTOR PASTE BY ADMIXING IT WITH A GLASS BINDER (EITHER BEFORE OR AFTER OXIDATION) AND A LIQUID CARRIER VEHICLE. THE PASTE IS PRINTED IN THE DESIRED PATTERN, DRIED AND FIRED TO PRODUCE THE RESISTOR IN FINAL FORM.

    Abstract: A CLASS OF CONDUCTIVE COMPOSITIONS FOR INTERCONNECTING PARTS IN THICK FILM CIRCUITS IS DISCLOSED WHEREIN CONDUCTOR PATHS ARE FORMED BETWEEN PARTICLES OF MICRON SIZE WHICH ARE COATED WITH NOBLE METAL OVER A CORE WITH CONTRASTING PROPERTIES WHEREBY AFTER FIRING, A SOLDERABLE ADHERENT CONDUCTIVE BODY IS FORMED WHICH HAS THE DESIRABLE PROPERTIES OF PRIOR-ART CONDUCTORS OF THE PALLADIUM-GOLD TYPE, BUT WHICH CONTAIN A SUBSTANTIALLY LESSER NOBLE METAL CONTENT. "MOCK-METAL" PARTICLES SUCH AS PALLADIUM OVER ALUMINA AND GOLD OVER COPPER ARE DESCRIBED.
