Foreign media: Chinese scientists have developed a carbide ceramic material that can withstand extreme high temperatures of up to 3600 degrees Celsius in an oxygen-containing environment, breaking through the thermal limit for hypersonic flight.
This achievement has important application potential in fields such as aerospace and energy.
Most materials currently fail below 3000 degrees. For example, SpaceX Starship's heat-insulating tiles can only withstand about 1371 degrees. High-temperature alloys degrade above 2000 degrees, and while carbon-carbon composites can endure 3000 degrees in inert environments, they rapidly oxidize and lose performance at 370 degrees in air.
The research leader stated that their team achieved this breakthrough by designing a high-entropy multi-component system, marking the first time this long-term limit has been surpassed globally.
