Summary

The production of alumina composites reinforced with lanthanum beta-alumina is investigated. The reinforcing phase was formed in-situ during sintering and yields full conversion to the desired composition. Reinforcement of alumina with this phase yields significant improvement in both strength and fracture toughness. Two processing routes were investigated, slip casting, and isostatic compaction and two different routes for lanthanum addition. The relation between processing and mechanical properties is evaluated.
