  • Lead silicate glass and a process for setting a reduced surface resistance of the lead silicate glass
    Patent number: 6420291
    Abstract: The invention relates to a lead silicate glass, to the use thereof for the production of secondary electron multipliers, and to a process for setting a reduced surface resistance of a lead silicate glass of this type. The lead silicate glass has the following composition (in % by weight): SiO2 15-35, PbO 35-55, Bi2O3>20-29, BaO 0-10, Cs2O 0-10, BaO+Cs2O 2-13, CaO 0-10, SrO 0-10, CaO+SrO+BaO 0-10, and up to 1% by weight of conventional fining agents. The surface resistance of the lead silicate glass after reduction in a hydrogen atmosphere is from 0.1 to 60 M&OHgr;/sq.
