Abstract Scope |
Cold sintering is an emerging powder processing methodology that enables the densification of ceramics and ceramic-based composites at significantly lower temperatures and shorter processing time comparing to conventional sintering processes. The immediate engineering impacts of the reduced ceramic processing temperatures not only enables energy-saving sustainable manufacturing practices but also densifications of thermodynamically metastable materials. Despite its unique technological importance, the fundamental understanding of cold sintering mechanochemical kinetics and densification mechanisms is still in the very early stages of the investigation. One of the crucial objectives for understanding its fundamental science is to predict densification behaviors under different processing conditions and to obtain a uniform microstructure at high density with controlled grain size. Based on the identified foundational knowledge of the cold sintering process where zinc oxide is used as a model system, pilot-scale manufacturing implementations and potential directions are discussed. |
