Energy efficient sintering of high-performance ceramics: Microwave cold sintering process (MW-CSP) (IMAGE)
Caption
Microwave cold sintering process (MW-CSP) was used to densify NaCl, KDP, MgMoO₄, Li₂MoO₄, and TiO₂ ceramics. Under the fundamental densification mechanisms dominated by the coupling of the transient liquid phase and microwave resonance densification mechanism, MW-CSP significantly reduced energy consumption by over 97%, lowered sintering temperatures by 225-500 °C, shortened processing times by 12.8-21.5 h, and improved mechanical and dielectric properties by 50-95%. This study demonstrates the enormous potential of MW-CSP as an efficient sintering strategy for preparing a variety of high-performance ceramics.
