Silicon Carbide Ceramics
Custom manufacturing ceramic tubes, pipes, and bushings
Silicon carbide (SiC) ceramic is a ceramic material made from silicon carbide powder that has many excellent properties.
First of all, silicon carbide ceramics have high hardness, which is second only to diamond and boron nitride, making it an ideal wear-resistant material. In addition, silicon carbide ceramics also have high strength, good corrosion resistance, oxidation resistance and low thermal expansion coefficient.
Secondly, silicon carbide ceramics also show good stability at high temperatures, and their high-temperature mechanical properties are the best among known ceramic materials. It can maintain strength and stiffness at high temperatures up to 1600°C or even 2000°C without plastic deformation and softening. This characteristic makes silicon carbide ceramics a high-quality high-temperature structural material, which is widely used in fields such as high-temperature bearings, bulletproof plates, nozzles, high-temperature corrosion-resistant components, and electronic equipment components in high-temperature and high-frequency ranges.
In addition, silicon carbide ceramics also have good thermal conductivity and electrical properties, and its thermal conductivity is second only to beryllium oxide ceramics among ceramics. This characteristic makes silicon carbide ceramics a high-quality refractory material that can be used to manufacture a variety of components that need to withstand high temperatures and have good thermal conductivity.
