The cold sintering process (CSP) is an innovative technique to densify ceramic powders at ultralow temperatures by applying uniaxial pressure and using a transient solvent. However, obtaining dense Li1.5Al0.5Ge1.5(PO4)3 (LAGP) ceramics, which have high ionic conductivity, by CSP has been a challengi...
