| Abstract Scope |
The processing of functional ceramics has advanced significantly over the past decade thanks to innovations in sintering technologies. Field Assisted Sintering Techniques (FAST) offer cost reductions by lowering sintering temperatures and times, while also solving challenges like grain growth, evaporation of volatile species, and chemical reactions. Our FAST/SPS (Spark Plasma Sintering) device can be adapted for other sintering methods, still using the integrated data logger for the parameters tuning. Ultra-fast high-temperature sintering (UHS) passes current through two carbon felts enclosing the specimen, while cold sintering (CS) achieves densification at low sintering temperatures through a solution precipitation creep mechanism. Here, we cover our ongoing research, featuring cold sintering of a proton-conducting material such as ceria- and yttria-substituted barium zirconate (BZCY) and UHS of strontium titanate (STO). Additionally, we are developing a modified UHS setup for sintering gadolinium-doped ceria (GDC) thin layers. The versatility of these sintering techniques is highlighted. |
