Title

Glass Properties in the Yttria-Alumina-Silica System

Abstract

The glass formation region in the yttria-alumina-silica system was investigated. Properties of glasses containing 25 to 55 wt% yttria were measured and the effect of the composition was determined. The density, refractive index, thermal-expansion coefficient, and microhardness increased with increasing yttria content. The dissolution rate in lN HCl increased with increasing yttria content and temperature. These glasses were also found to have high electrical resistivity.
