Ethan Ellis (Lucideon)Sintering of specific material systems4. Poster presentation
Advanced ceramics possess admirable properties, such as high operating temperatures and low thermal conductivity, that make them well-suited for extreme environments, including those in the aerospace and nuclear industries. One of the most significant drawbacks of ceramics is the challenge of processing, particularly in the production of ultra-high-temperature ceramics (UHTCs), which must be...

Ni-based superalloys are widely used in the hot sections of gas turbines due to their high melting points and mechanical strength. To protect these components from extreme temperatures, refractory ceramic thermal barrier coatings (TBCs) are applied. Recently, efforts to replace liquefied natural gas (LNG) with hydrogen fuel have been pursued to reduce greenhouse gas emissions. However,...

The energy transition towards sustainable mobility is essential to reducing CO₂ emissions and combating climate change. The global expansion of electromobility, the electrification of industry, and the use of wind energy will significantly increase the demand for high-performance NdFeB magnets. In addition to recent efforts to expand magnet production outside of China, recycling end-of-life...

Copper (Cu) powders for low-temperature sintering are capable of bonding at temperatures significantly below their melting point. Consequently, they are expected to be applied in die-attach materials for power modules designed for high-temperature operation.
To achieve low-temperature sintering, it is effective to refine the particle size. In the case of Cu, an anti-oxidation coating which...

High-entropy ceramics are promising materials for advanced optical applications, particularly for their enhanced thermal stability and tunable spectral properties. However, achieving full density and eventually optical transparency remains challenging in multicomponent systems, as sluggish diffusion kinetics can hinder pore elimination. Furthermore, chemical complexity increases the risk of...

Transparent Gd2O3–MgO composite ceramics are promising materials for mid-wave infrared (MWIR) window applications due to their good optical transparency and thermal stability. However, the sintering behaviour and microstructure evolution of the two-phase system are strongly influenced by the phase transition of Gd2O3 and the phase compatibility between Gd2O3 and MgO, which significantly affect...

Dr Yiquan Wu (New York State College of Ceramics, Alfred University)Sintering of specific material systems3. Oral presentation
Non-oxide ceramics such as ZnS and ZnSe are highly transparent across a broad spectral range of 0.5–18.0μm, positioning them as promising candidates for various scientific and technological applications. While chemical vapor deposition (CVD) remains an effective method for producing transparent ZnS and ZnSe ceramics, its high cost and time-intensive nature present notable drawbacks....
