Ablation behaviour of Cf–ZrC-SiC with and without rare earth metal oxide dopants
Open Ceramics, 2022 Continuous carbon fibre/carbon composites are candidates for ultra-high temperature applications due to their ability to retain their strength at elevated temperatures, however they easily oxidize and ablate in high temperature oxygen-based environments,

A novel microstructural design to improve the oxidation resistance of ZrB2-SiC ultra-high temperature ceramics (UHTCs) [PDF]
Journal of Alloys and Compounds, 2019 Abstract Directionally Solidified 72.8 mol% ZrB2 - 27.2 mol% SiC (equivalent to 20 vol%) composite was fabricated using a crucibleless-melting technique. Microstructural and XRD analyses confirmed the texturing of grains and lamellar structure. The Lotgering (00l) orientation factor was as high as 0.97.

UHTCs: Ultra-High Temperature Ceramic Materials for Extreme Environment Applications
The Electrochemical Society Interface, 2007 3000°C. That’s not just hot … it’s EXTREMELY hot. It is above the melting or decomposition temperatures for most of the materials known to man. But in the world of extreme environment engineering, it is just a baseline.
