Glasses with high content of silver oxide
Abstract
Abstract GLASSES HAVING A HIGH CONTENT OF SILVER OXIDE ARE DESCRIBED. GENERALLY THESE GLASSES CONTAIN AT LEAST 20%, AND UP TO AS HIGH AS 70% SILVER OXIDE EXPRESSED AS AG2O. THE GLASSES ALSO CONTAIN A METAL OXIDE OF ONE OF THE METALS, VANADIUM (V), TUNGSTEN (W), MOLYBDENUM (MO), URANIUM (U) OR MANGANESE (MN), AND AN OXIDE OF ONE GERMANIUM (GE), ARSENIC (AS), ANTIMONY (SB), BISMUTH GERMANIUM (GE), ARSENIC (AS), ANTIMONY (Sb), BISMUTH (BI) OR TELLURIUM (TE), ALTENATIVELY, THE GLASS MAY CONTAIN IN ADDITION TO THE AG2O COMPONENTL A MIXTURE OF OXIDES OF THE ABOVE TRANSITION ELEMENTS. THE GLASSES ARE PRODUCED BY FORMING A MELTUSING SILVER IN THE FORM OF AGNO3 TO THEREBY ENABLE FORMATION OF GLASSES WHICH MAY HAVE CONSIDERABLE QUANTITIES OF AG2O WITHOUT PRECIPITATING THE SILVER OUT IN THE METALLIC FORM. THE GLASS COMPOSITIONS ARE CHARACTERIZED BY LOW MELTING AND LOW SOFTENING YEMPERATURES, HIGH DENSITY, HIGH REFRACTIVE INDEX, GOOD INFRARED TRASMISSION CHARACTERISTICS AND WATER RESISTANCE. USES FOR THE GLASSES INCLUDE FIBER OPTICS, CONDENSERS, AND GLASES FOR SUBSTRATES FOR MICROELECTRONIC CIRCUITS.
