| Abstract Scope |
Among many materials present in our daily lives, technical ceramics occupy numerous fields. Their applications range from energy, biomedical to transport (automotive, aeronautics, space…) sectors. Sintering is a key processing of the powder metallurgy to produce ceramics with desired physical performances. It determines both the densification (porosity rate) and the microstructure (grain size) as well as the shape of the part. In the last decades, the development of more energy efficient and environmentally friendly manufacturing processes has encouraged intensive research on low-temperature and/or ultrafast sintering processes. These efforts have led to the elaboration of new materials, multi-materials and composites for applications in various socio-economics fields. In this communication, we will illustrate how low temperature sintering processes: Cold Sintering Process (CSP) and Cold-Spark Plasma Sintering (Cold-SPS) separately or combined can allowed to develop nanostructured oxide ceramics with improved properties. The complex chemical mechanisms involved in the process of densification are highlighted. |
