Scientists develop the most heat-resistant material ever created:
A group of scientists from NUST MISIS developed a ceramic material with the highest melting point among currently known compounds. Due to the unique combination of physical, mechanical and thermal properties, the material is promising for use in the most heat-loaded components of aircraft, such as nose fairings, jet engines and sharp front edges of wings operating at temperatures above 2000 degrees C.
[...] During recent developments, the goal of the scientists was to create a material with the highest melting point and high mechanical properties. The triple hafnium-carbon-nitrogen system, hafnium carbonitride (Hf-C-N), was chosen, as scientists from Brown University (U.S.) previously predicted that hafnium carbonitride would have a high thermal conductivity and resistance to oxidation, as well as the highest melting point among all known compounds (approximately 4200 degrees C).
Using the method of self-propagating high-temperature synthesis,the NUSTMISIS scientists obtained HfC0.5N0.35, (hafnium carbonitride) close to the theoretical composition, with a high hardness of 21.3 GPa, which is even higher than in new promising materials, such as ZrB2/SiC (20.9 GPa) and HfB2/SiC/TaSi2 (18.1 GPa).

The material is meant for spaceplanes.

Other than the melting point, it would seem that it's almost the opposite. Starlite is known for its low thermal conductivity and is relatively fragile. This new material is a poor insulator and high strength. Still a useful material, just not in the same applications.

Put an insulating layer under it and you're golden. Hafnium carbonitride to conduct the heat over a large surface area without melting, insulating layer to block it.

Of course the Russians wil be using it soon in their rockets.
However, stolen? No, not yet.
I mean, US will need to put some effort into getting the technology out from the National University of Science and Technology MISiS (Russia) [wikipedia.org]

Fsck. Was looking at that list and thought it odd that they'd listed all the female members of the team first and then checked the original ref, it's a cuntpaste error, it should read "V.S.Buinevich, A.A.Nepapushev, D.O.Moskovskikh et al". Hope the authors aren't too upset at the inadvertent sex change by the Soylent editors.
