ABSTRACT:
A family of glasses from the SiO2—Al2O3—P2O5ternary system exhibiting high strain point, transparency, and low coefficient of thermal expansion. The glasses have the following composition, expressed in mol percent and calculated from the glass batch on an oxide basis: 55-80 SiO2, 12-30 Al2O3, and 2-15 P2O5.
