Title: Salt ceramic composites and manufacture thereof

Abstract

Highly dense lithium based ceramics can be prepared by a low temperature process including combining a lithium based ceramic with a polar solvent having a lithium based salt dissolved therein and applying pressure and heat to the combination to form a salt-ceramic composite. Advantageously, the lithium salt is one that dissolves in the polar solvent and the heat applied to the combination is no greater than about 250° C. Such composites can also have high ionic conductivity.
