Abstract

A new composition for electrovacuum lead glass with a 20 wt. % PbO has been synthesized. The system of loading the charge and glass scrap into a furnace and a new system of tube shaping are described. The effect of the moisture content of the charge and the temperature on volatilization of PbO, Na2O, and K2O is investigated. It is shown that an artificially formed protective layer on the surfaces of discharge channels considerably reduces the volatilization of PbO, Na2O, and K2O from the liquid glass. Practical recommendations are presented.
