Silicon carbide ceramic material
With the development of science and technology, especially the rapid development of energy and space technology, materials are often required to have superior properties such as high temperature resistance, corrosion resistance, and wear resistance in order to be used in harsh working environments. Special ceramic materials have become cutting-edge due to their excellent properties such as strong oxidation resistance, good wear resistance, high hardness, good thermal stability, high high-temperature strength, small thermal expansion coefficient, high thermal conductivity, and resistance to thermal shock and chemical corrosion. An important part of science that is universally valued.
Silicon carbide ceramics are a new material that has only begun to develop in the past twenty years. However, due to its particularly excellent high strength, high hardness, corrosion resistance, and high temperature resistance, it has been quickly developed and used in petrochemical and metallurgical industries. Machinery, aerospace, microelectronics, automobiles, steel and other fields, and increasingly show advantages that other special ceramics cannot match.
The rapid development of modern national defense, nuclear energy and space technology, as well as the automobile industry and marine engineering, has placed increasingly high demands on materials such as rocket combustion chamber linings, aircraft turbine engine blades, nuclear reactor structural components, high-speed pneumatic bearings and mechanical seal parts. A variety of new high-performance structural materials need to be developed.
Silicon carbide (SiC) ceramics have excellent properties such as high high-temperature strength, strong oxidation resistance, good wear resistance, good thermal stability, small thermal expansion coefficient, high thermal conductivity, high hardness, and resistance to thermal shock and chemical corrosion. Therefore, it has shown its talents in many fields and is increasingly valued by people.
For example,
SiC ceramics have been widely used in various corrosion-resistant containers and pipes in the petrochemical industry;
It has been successfully used as various bearings, cutting tools and mechanical seal components in the machinery industry;
It is also considered the most promising candidate material in the aerospace and automotive industries for future manufacturing of gas turbines, rocket nozzles and engine components.
