Displacement characteristics of a glass-ceramic insulator in a vacuum tube envelope sealing process
The objective of the study was to examine the flow characteristics of two glass-ceramic compositions (used for high voltage insulation in a vacuum tube envelope) during sealing to molybdenum by determining the temperature at which the glass starts to flow and the temperature at which it becomes fully deformed. The initial softening temperature was between 630 and 715/sup 0/C; the deformation temperature ranged from 890 to 1010/sup 0/C.
