Ultra-High Temperature Ceramics are a family of compounds that display a unique set of properties, including extremely high melting temperatures (>3000°C), high hardness and good chemical stability and strength at high temperatures. UHTC materials are typically considered to be the carbides, nitrides, and borides of the transition metals, but the Group IV compounds (Ti, Zr, Hf) plus TaC are generally considered to be the main focus of research due to the superior melting temperatures and stable high-melting temperature oxide that forms in situ. The combination of properties make these materials potential candidates for a variety of high-temperature structural applications, including engines, high-speed vehicles, plasma arc electrodes, advanced nuclear fuels, fusion first walls and divertors, cutting tools, furnace elements and high temperature shielding.
The development of structural materials for use in oxidizing and rapid heating environments at temperatures above 1600°C is therefore of great engineering importance. For the past two decades researchers have built on a resurgence in exploration of UHTCs and have expanded the scope of engineering and design using these novel materials. Topics such as incorporating UHTCs in fiber reinforced composites; investigating unique high entropy carbides and borides, and expanding the field of MAX phases have all led to new developments. The purpose of this meeting is to thus bring together interested parties from academia, government and industry in a single forum that allows the bench researchers to interact with designers and engineers to discuss state-of-the-art research and development efforts, what the results mean in a broader context and how to move the technology forward toward near-term and longer term use.
