ABSTRACT:
A glass composition is disclosed that is useful as a solder glass for sealing components together. However, the glass is also especially adapted for use as an electric resistance film for coating the inner neck or funnel portions of a cathode ray tube to reduce arcing. The glass composition includes primarily the oxides of vanadium and phosphorous with the preferred addition of either zinc oxide or lead oxide. Still other metal oxides may be optionally included such as oxides of barium, antimony, lithium, manganese, silicon, boron, molybdenum and mixtures thereof.
