ABSTRACT:
Doped quartz glass is produced by fusing a mixture of quartz powder with a concentrate. The concentrate consists of quartz powder and the oxides of alkaline earth metals and/or alkali metals (dopants). By adding a small quantity of dopants, a doped quartz glass can be obtained having a viscosity behavior corresponding to that of Vycor glass. Still softer glasses can be obtained by the addition of some more dopants.
