Roadmap for densification in cold sintering: Chemical pathways

The cold sintering process (CSP) is a technique that enables densification of ceramics and composites at extremely low temperatures (T < 400 °C) with the application of a uniaxial pressure and a transient solvent. At the laboratory scale, comparing direct sintering methods relative to CSP evid...
