WebMar 1, 2024 · Porous ultra-high-temperature ceramics (UHTCs) are a candidate group of materials for transpiration cooling of hypersonic vehicles due to their exceptionally high melting point, typically above 3000 K. Their high operating temperature permits a higher amount of radiative cooling than that achievable with conventional materials, which … WebMay 10, 2024 · Shock-Induced Melting of a Porous Solid: When materials experience sudden, impulsive loading via impact, shock waves travel through those materials …
WebAs for properties, it has low thermal conductivity, high thermal expansion coefficient, and low thermal shock resistance. However, it has a fairly low operating limit of 1200°C due to phase instability, and can corrode due to its oxygen transparency.
