Gold composition for bonding gold to a ceramic substrate utilizing copper oxide and cadmium oxide
Abstract
Abstract A COMPOSITION FOR, AS WELL AS A METHOD OF BONDING GOLD TO A CERAMIC SUBSTRATE AND A BONDED GOLD ARTICLE WHICH INCLUDES A COMPOSITION OF GOLD, COPPER OXIDE, AND CADMIUM OXIDE FOR BONDING A GOLD LAYER TO A CERAMIC SUBSTRATE. GOLD POWDER, COPPER OXIDE PARTICLES AND CADMIUM OXIDE PARTICLES OLEFINE A SOLID COMPOSITION MIXTURE WHERE THE COPPER OXIDE HAS A WEIGHT PERCENTAGE IN THE PREFERRED REGION BETWEEN 0.25% AND 3.0% AND THE CADMIUM OXIDE HAS A WEIGHT PERCENTAGE IN THE PREFERRED REGION BETWEEN 1.0% AND 5.0% ORGANIC BINDER IS ADDED TO A PREDETERMINED AMOUNT OF THE COPPER OXIDE AND CADMIUM PARTICLES AND THEN BLENDED. THE GOLD POWDER IS INCORPORATED INTO WITHIN THE RANGES OF 10% TO 95%. THE TOTAL COMPOSITION FORM A TOTAL COMPOSITION MIXTURE. THE ORGANIC BINDER HAS A WEIGHT PERCENTAGE OF THE TOTAL COMPOSITION MIXTURE MIXTURE IS BLENDED AND APPLIED TO A CERMAIC SUBSTRATE, MIXTURE IS BLENDED AND APPLIED TO A CERMAIC SUBSTRATE, THE COATED CERAMIC ARTICLE IS FIRED WTHIN THE PREFERRED TEMPERATURE RANGE 950*C. TO 1000*C. COPPER OXIDE CRYSTALS IMPREGNATE THE CERAMIC SUBSTRATE AND FORM A HIGH STRENGTH BOND BETWEEN THE GOLD LAYER AND THE CERAMIC SUBSTRATE.
