Abstract

For the synthesis of crystalline LAS glass by sol-gel method, the effect of operation conditions including metal alkoxide ratio, nucleating agent composition and heat treatment on the crystalline properties was experimentally investigated. The gelation time and crystallization temperature were proportionally affected by the mole ratio of TEOS in metal alkoxides solution. The addition of TiO2 had an influence on the increasing of the gelation time, but the crystallization temperature was rarely dependent on the adding of nucleating agent. The crystallinity of LAS glass was improved by the nucleating agent under same heat treatment conditions.
