Recently, the cold sintering process (CSP) was unveiled as a technique that enables the sintering of ceramics at low temperatures (T=350 °C)10 based on a pressure solution creep mechanism (dissolution mass transport precipitation) induced by the presence of a transient liquid and uniaxial pressure.11 Several experimental and theoretical studies by ReaxFF molecular dynamics highlighted that the sintering temperature of ZnO with this process can be as low as 120 °C thanks to solvent-induced accelerated diffusional processes and chemical effects.12–15 Sintering is typically described as a thermally or mechanically and thermally driven mass transport process to minimize the surface energy of a particle ensemble. For most of the sintering techniques, the ratio between the sintering temperature (Tsint) and the melting temperature (Tmelt), is in the range of 0.5 < Tsint/Tmelt < 0.95.16 For cold sintering, this sintering criterion ratio is drastically lower as Tsint/Tmelt can be below 0.2. This opens many new opportunities in terms of the low temperature fabrication of materials, devices and the integration of all material types, namely ceramics, polymers and metals to fabricate all types of composites. As an example, the CSP enabled the fabrication of functional ceramic-polymer composites with a high-volume fraction of ceramic (up to 99.9 %) thanks to the matching of processing temperature windows of ceramic and polymers.17 The fabrication of dense ceramic-polymer composites, with thermoplastic or thermosetting polymers distributed at the interfaces between adjacent ceramic grains18 was demonstrated for multiple applications such as batteries, electronics, wave propagation among other things: Li2MoO4-PTFE (polytetrafluoroethylene)19, Li1+x+yAlxTi2-xSiyP3-yO12 (LATP) with bis(trifluoromethanesulfonyl)imide (LiTFSI) salts showing similar room temperature conductivity (10-4 S.cm-1), comparable to conventionally sintered ceramics20 (1-x) SiO2-xPTFE14 and ZnOCa3Co4O9-PTFE.21 Recently, Zhao et al. presented a new type of nanocomposite structure consisting of ceramic (ZnO) and polymer phase (PTFE- Polytetrafluoroethylene) that provides characteristic varistor I-V behavior.22 Additionally, Hérisson de Beauvoir et al. exhibited applicable of the integration of metallization of different metal types (i.e. Fe, Cu, Al) into functional electroceramic with cofiring process as a multilayer form by the enormously low sintering temperature that can be called as “cold sintering co-fired ceramic (CSCC)” process that is the first time in the literature.23
