Solution-assisted densification of NaSICON ceramics
| DWPI Title: Fabrication of dense ceramic for e.g. solid electrolyte, involves adding solvent to powder of sodium super-ionic conductor particles to dissolve particles and applying sintering pressure and sintering temperature to reprecipitate particles |
| Abstract: A sodium-ion conducting NaSICON ceramic can be densified via the addition of a solvent to a NaSICON powder and subsequent pressing under high pressure and mild heat. Densification to ˜90% relative density can be achieved, providing a path toward low-temperature fabrication of Na-ion conductors. |
| Use: Fabrication of dense sodium super-ionic conductor ceramic. Uses include but are not limited to solid electrolyte in sodium-ion battery, chemical purification, chemical sensing, and treatment of radioactive waste. |
| Advantage: The method enables low-temperature fabrication of dense sodium super-ionic conductor ceramic under high pressure and mild heat. |
| Novelty: Fabrication of dense sodium super-ionic conductor (NaSICON) ceramic involves providing a powder of NaSICON particles, adding a solvent to the powder to partially dissolve the particles in the solvent to obtain a dissolved solution, and applying appropriate sintering pressure and sintering temperature to the dissolved solution to reprecipitate particles. |
