Key materials for future technological development-black silicon carbide
Black silicon carbide,also called black carborundum or black SiC,is produced in electrical internal resistance furnaces from high purity silica sands and petroleum coke.
Because black silicon carbide has its unique physical properties such as high hardness,stable chemical properties,high thermal conductivity, small thermal expansion coefficient, good wear resistance,Corrosion resistance, etc.which makes it work widely in many fields.
A Revolutionary in the Semiconductor Industry
In the field of semiconductors, silicon carbide powder is the cornerstone of manufacturing wide bandgap semiconductor devices. Compared with traditional silicon-based semiconductors, silicon carbide-based semiconductors have higher breakdown voltage, faster switching speed and lower power consumption. These characteristics make silicon carbide-based power electronic devices widely used in electric vehicles and solar inverters. It has shown unparalleled advantages in high-energy-efficiency applications such as machines and high-speed trains. It can not only significantly improve energy conversion efficiency, but also open up new possibilities for miniaturization and lightweighting of equipment.
The patron saint of aviation and aerospace
Faced with the challenges of extreme environments, silicon carbide powder has found its place in the aerospace field due to its excellent high temperature resistance and oxidation resistance. From the thermal protection system of rocket engines to the structural components of satellites, silicon carbide-based composite materials can withstand thousands of degrees of high temperature without deformation, effectively protecting key equipment from the erosion of the harsh space environment and ensuring the successful execution of the mission.
The darling of high-performance ceramics
Silicon carbide powder is also indispensable in the manufacture of high-performance ceramics. Through precise molding and sintering processes, it can be transformed into ceramic materials with high strength, wear resistance and corrosion resistance. It is widely used in mechanical seals, chemical equipment, automotive brake pads and other fields, greatly improving the durability and reliability of the products.
Conclusion
Silicon carbide powder, a seemingly simple powder, actually carries the important mission of promoting scientific and technological progress and sustainable development. With the continuous progress of materials science and the increasing maturity of application technology, the application field of silicon carbide powder will be broader, and its role in the future scientific and technological stage will become more and more important. Let us look forward to how this future material star will continue to illuminate the path of human exploration of the unknown and pursuit of excellence.
