The silicate glass containing lead, its use and method of adjustment of a reduced surface resistivity of such a glass containing lead silicate

摘要

The invention relates to a silicate glass containing lead to its use for the manufacture of multipliers of secondary electrons, as well as a method of adjustment of a surface resistivity of such a silicate glass containing lead. The silicate glass containing lead has the following composition (in% by weight): sio2 15 - 35, pbo 35 - 55, bi2 o3 20 - 29, bao 0 - 10, cs2 o 0 - 10, bao + cs2 o 2 - 13, cao 0 - 10, sro 0 - 10, cao + sro + bao 0 - 10, and up to 1% by weight of refining agents the usual. The surface resistivity of the silicate glass containing lead, after reduction in an atmosphere of hydrogen is between 0, 1 and 60 momega / square.
