Scientists from the Institute of Strength Physics and Materials Science at the Siberian department of the Russian Academy of Sciences have developed an innovative ceramic composite that can self-heal their defects or damage.
This ceramic is scheduled to be used for the thermal protection of high-energy systems and high-speed aircraft (i.e., drones.)
At certain temperatures, a glass coating develops on the ceramic surface, which prevents oxygen molecules from penetrating inside, ensuring that cracks that may occur during the use of the ceramics “self-heal.” As a result, the self-healing process takes only about ten minutes.
The strength of the ceramic is similar to that of the diamond. However, it also has a higher resistance to hot temperatures and can withstand even 2700 degrees Celsius. So, it can be used in a wide range of areas, including space engines, aircraft turbines, and other objects exposed to high temperatures.
