Effect of Electric Current on Mass Transfer in S78-4 Lead-Silicate Glass

Abstract

The results of an investigation of the processes occurring during heating and isothermal soaking at 450°C with electric current transmission through a sample of S78-4 lead-silicate glass, widely used in electronics, are presented. The change in electric conductivity versus the temperature and the annealing time with a continuous unidirectional current as well as with an alternating current (which eliminates electric mass transfer) flowing through the sample were obtained. The results obtained can be used to improve existing and develop new technological processes for producing electronics components using lead-silicate glass.
