Abstract

In gas panel fabrication, annular glass preforms of divitrifying or mixed phase seal glasses are used to seal the tubulation member to the rear plate of the panel. Such glasses are relatively unstable in the temperature ranges encountered in the fabrication process so that physical parameters, such as the thermal coefficient of expansion and flow characteristics, tend to vary. A manufacturing process which eliminates these problems is described below.
