Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> MXene-Zirconium Diboride Based Ultra-High Temperature Ceramics. [PDF]
Adv Sci (Weinh)This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...

High temperature oxidation of tantalum carbide (TaC) powder.
Journal of Advanced Science, 1998 The high temperature oxidation of tantalum carbide (TaC) powder was investigated in order to determine the application of refractory materials for space crafts and rocket vehicles. TaC powder with an average particle size of about 10μm was used in this experiment. The samples were oxidized at 573 to 1273K for 5min to 25h in air. The weight changes were

Abnormal Structure of Tantalum Carbide Phase in WC-TaC-Co Alloys
Journal of the Japan Society of Powder and Powder Metallurgy, 1968 The WC-TaC-Co alloys containing less than 5%TaC (sintered at 1350°C or 1400°C for lhr) were used as specimens. Their hardness, transverse-rupture strength, density and microstructures were examined, and the effects of the abnormal structure, i.e., spotty structure of tantalum carbide phase on the mechanical properties were studied.

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.The local carbon environment in the refractory transition metal carbides ZrC, HfC, NbC, and TaC was studied using high‐resolution magic angle spinning 13C NMR spectroscopy. Results show that carbon nuclei with next nearest neighbor vacant sites or oxygen/nitrogen impurities are distinguishable through 13C NMR, and that the technique can be used to ...

Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers
Advanced Materials, Volume 38, Issue 19, 1 April 2026.Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Energy Technology, Volume 14, Issue 1, January 2026.Mechanochemically synthesized Cr3C2 and Mo2C, incorporated in a polyurethane‐based binder matrix, and applied to stainless steel, show the lowest contact resistance. The Cr3C2 coating provides good corrosion performance, while the Mo2C coating is unable to protect the metal from corrosion.
