ABSTRACT:
A substrate for flat panel display glasses comprising a glass the P2O5—SiO2—Al2O3ternary system which yields stable glasses exhibiting high strain point temperatures, resistance to devitrification, good chemical durability, excellent dielectric properties, coefficients of thermal expansion that can be tailored to match that of silicon, and having liquidus viscosities that enable forming by conventional methods. The glass comprises the following composition as calculated in weight percent on an oxide basis: P2O533–75%, SiO22–52%, Al2O38–35%.
