Abstract A novel reactive infiltration processing (RIP) technique was employed to infiltrate porous carbon fibre reinforced carbon (C/C) composite hollow tubes with ultra high temperature ceramic (UHTC) particles such as ZrB 2 . The C/C composite tubes had initial porosity of ∼60% with a bimodal (10 μm and 100 μm) pore size distribution.

Mass Production and Assembly of Ultra-High Temperature Ceramic (UHTC) Nanowires: TiC
ECS Meeting AbstractsUltra-high temperature ceramics (UHTCs), typically the non-stoichiometric carbides and nitrides of metal such as Ta, Zr and Ti, have melting temperatures higher than 3000oC.(1) They also have excellent mechanical properties, such as hardness and wear resistance.

Abstract MoSi2 based ceramics have great potential for high temperature heating element applications. In this paper, MoSi2-UHTC ceramics were produced by pressureless sintering by introducing ZrB2-20 vol% SiC ultra high temperature ceramic as additives. The key issues of the MoSi2-UHTC ceramics for ultra high temperature heating element applications,

High-Entropy Alloys (HEAs) have attracted considerable interest due to the combination of useful properties and enhanced applications, and a few HEAs have already been shown to possess exceptional properties under extreme conditions (e.g. Ultra-High Temperature Ceramic (UHTC)). However, predicting the formation, structures, and stability of HEAs is one
