Shiji Shen (City University of Hong Kong / City University of Hong Kong, Dongguan)Ultra-fast High Temperature Sintering UHS4. Poster presentation
Positive mixing-enthalpy systems such as Cu-Fe are difficult to process because liquid-phase immiscibility drives phase segregation and weak interfaces during conventional sintering. Building on ultrafast high-temperature sintering (UHS), we introduce ultrafast high-temperature sintering-quenching (UHSQ), where rapid Joule-heating sintering is immediately followed by ultrafast quenching to...

Vat photopolymerization 3D printing has emerged as a promising additive manufacturing (AM) technology for producing high-precision ceramic components. However, long post-processing times remain a significant challenge for industrial implementation. To address this limitation, the present study systematically investigates the effects of Ultrafast High-Temperature Sintering (UHS) processing...

Rapid heating is a cornerstone of modern sintering approaches like flash sintering, ultrafast high temperature sintering (UHS), fast firing, microwave sintering, or spark plasma sintering. Besides the technological interest, fundamental answers are emerging about how the heating rate can tailor the ceramic structure from the micro- to the nano-scale.

Mr Joao L. Miranda (CICECO - Aveiro Institute of Materials, University of Aveiro)Ultra-fast High Temperature Sintering UHS3. Oral presentation
The transition from lead-based to lead-free piezoelectrics is currently a key challenge in the electroceramics community, which aims to find suitable sustainable materials. In the last decade, the solid solution barium calcium zirconate titanate (BCZT) has received increased attention for room temperature applications due to high piezoelectric coefficient and remnant polarisation. The high...

Sintering of functional ceramics remains a critical and cost-intensive step in the manufacturing of advanced electrochemical devices. This challenge is amplified in multilayer systems requiring different sintering temperatures, such as solid oxide cells (SOC). Conventional manufacturing relies on prolonged high-temperature exposure to promote particle connectivity; however, grain growth is...

Prof. Vincenzo M. Sglavo (Department of Industrial Engineering, University of Trento)Ultra-fast High Temperature Sintering UHS2. Invited speaker (by invitation only)
Ultra-rapid high-temperature sintering has recently been proposed as a technique that enables the densification of ceramic materials in extremely short timeframes, thereby saving a considerable amount of energy. The process is based on the rapid heating of a carbon felt—in which the sample is placed—via Joule heating generated by an electric current. This approach is highly attractive for...

High-entropy alloys (HEA) are promising candidates as low-cost and precious metal-free catalysts for the alkaline exchange membrane (AEM) electrolysis. For this application, sputtering targets which require a pure phase composition, homogeneous microstructure, and high density, can be produced via FAST/SPS.
However, there is a challenge of sintering a single phased HEA without unwanted pore...
