Zirconia ceramics as thermal insulation materials in aerospace

Release time：2024-09-18click：0

Zirconium oxide ceramicAs ahigh temperature resistant ceramic, and has strong thermal insulation properties, so it is very suitable for use as a heat-resistant material, and this heat-resistant material can also be used in aerospace. The following will briefly introduce the use of zirconia ceramics as a heat-resistant material. Applications in aerospace.

In the field of aerospace, scientists are constantly developing faster and safer aircraft to meet passengers' pursuit of a fast and comfortable travel life and human beings' requirements for exploring the mysterious world of the universe. The heat-resistant material used on the wings of the space shuttle Columbia is made of ceramic materials. It is conceivable that if this material has high enough strength and can still maintain good condition even when it suffers some inevitable damage, then the tragedy of the "Columbia" crash can be avoided.

In order to ensure that future space shuttles have more reliable flight safety, NASA quickly launched relevant research plans after the Columbia crash, including research on new A generation of ultra-high temperature ceramics used in space shuttle thermal insulation materials.

In addition to being used as heat-resistant materials for space shuttles, the applications of ultra-high-temperature ceramics in the aerospace field include heat-resistant protective materials for supersonic aircraft, fuel nozzles for rockets and various high-speed aircraft. When aircraft fly at supersonic speeds, they will friction with the air and produce very high temperatures. Ultra-high temperature ceramics have good heat resistance and can avoid damage to zirconia inside high-temperature aircraft. To overcome the gravity of the earth and achieve high-speed flight, a rocket must have strong propulsion capabilities, so there must be extremely high combustion temperatures at the fuel nozzle, and general materials are difficult to meet the needs of this application. This is where ultra-high temperature ceramics come in. .

Currently, there is an upsurge in researching ultra-high-temperature ceramics around the world. With the application of a number of high-performance materials, it will lead to a rise in the aerospace field.create a new revolution. As a key material on aerospace vehicles. Ultra-high temperature ceramics will play the role of protector and help people continue to break through the limits of speed and space.
