Abstract
A reduced temperature route is explored for the preparation of ceramics with NASICON composition. The procedure includes sol-gel synthesis, Sample Controlled Thermal Analysis of the precursor powders and hot-pressing the powders under 0.3 GPa and at temperatures between 600 and 900∘C. It is shown that ceramics with densities around 90% can be obtained by this route. Electrical conductivity values and activation energies are determined and discussed.
