  • Composition and method of bonding gold to a ceramic substrate and a bonded gold article
    Patent number: 3969570
    Abstract: A composition for, as well as a method of bonding gold to a ceramic and a bonded gold article which includes a composition of gold and copper oxide for bonding a gold layer to a ceramic substrate. Gold powder and copper oxide particles define a solid composition mixture wherein the copper oxide has a weight percentage in the preferred region between 1.2% and 1.4%. Organic binder is added to a predetermined amount of copper oxide particles and blended. The gold powder is incorporated into the copper oxide and organic binder to form a total composition mixture. The orgaic binder has a weight percentage of the total composition mixture within the preferred range of 50% to 85%. The total composition mixture is blended and applied to a ceramic substrate. The coated ceramic article is fired within the preferred temperature range 1020.degree.C. to 1040.degree.C. Copper oxide crystals are formed which impregnate the ceramic substrate and form a high strength bond between the gold layer and the ceramic substrate.

  • Bonded gold article composition for bonding gold to a ceramic substrate utilizing copper oxide and cadium oxide
    Patent number: 3935366
    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 define 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 the copper oxide, cadmium oxide, and organic binder to form a total composition mixture. The organic binder has a weight percentage of the total composition mixture within the ranges of 10 to 95%. The total composition mixture is blended and applied to a ceramic substrate. The coated ceramic article is fired within the preferred temperature range 950.degree. to 100.
