Phase-Transition in, Thermal History and Expansion of NASICON, Solid-Solution and Lithium Derivative Ceramics and of SiC (Mullite) Fibers NASICON Composites
The thermal expansion of NASICON ceramics has been examined as a function of the composition (phosphate to silicate solid solution, sodium and lithium derivatives) and as a function of the thermal history. Results are discussed at the light of structural changes (monoclinic to rhombohedral transition, water traces, etc.). Comparison is made between monolithic ceramics and SiC and/or aluminosilicate fiber, NASICON matrix composites.
