Abstract

Glass-ceramic composites were successfully fabricated by incorporating amorphous lithium aluminosi Iicate (LAS) particulates into a silica gel matrix. LAS volumes in the composites were varied from 50 to 75%, and all composites were easily cast, dried and fired without segregation or cracking. Elevated temperature processing resulted in crystallization of the LAS into a P-spodumene solid solution phase as well as densification of the gel-derived glass matrix. An inverse relationship was found between densification efficiency and LAS volume percent.
