Scientists from the Chinese Academy of Sciences Institute of Physics Sciences developed a new ceramic Airgoel Si@sio2It has high anisotropic thermal conductivity and extraordinary heat stability. In the aviation industry, the material can find applications in other areas where energy and reliable thermal insulation is required. The results of the study have been published scientifically magazine Advanced Science.
Development is inspired by natural structures such as layered architecture of wood vascular system or silkworm cocoons. These natural structures effectively control heat due to internal organization.
For the production of an Airgoel, researchers used a combination of electrical and sublimation drying methods.
At first, thermal striking Nano -Silicone Carbide (Sic), which has high chemical stability, was synthesized. Then, an amorphous shell made on the surfaces of silicone dioxide (SIOâ‚‚) was applied. This coating acts as a phonon barrier that provides both in -layer alignment and a layer of layer, which gives the material a high guidance and order.
According to experts, Airgel features features at a wide variety of temperatures from -196 ° C to 1300 ° C, which makes it ideal for the receiving and other excessive environment conditions.
Previously, scientists Created Airgelle cooling surfaces due to air glow.
