Physical Property Changes of a Lithia-Alumina-Silica Based Glass as a Function of Composition

摘要

The effect of compositional changes on various physical properties (coefficient of thermal expansion, crystalline phases, and refractive index) both before and after devitrification (when appropriate) on a lithia-alumina-silica-based glass was determined. The results obtained by adding or subtracting various amounts of the compositional oxides (lithium carbonate, potassium carbonate, ammonium phosphate, alumina, boric acid, or silica) one at a time showed that compositional changes had a pronounced influence on the resultant physical properties of these glasses.
