Solution-assisted densification of NaSICON ceramics

Patent ·
OSTI ID:1987211
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.
