Silicon carbide offers high hardness, high strength, and high thermal conductivity — characteristics that are superior to alternatives such as glass, glass-ceramics, and metals that are often used for reflective optical systems.
Silicon Carbide (SiC) Silicon carbide (SiC) is a material that can withstand high temperatures of 1400 and higher and is resistant to thermal shock. Additionally, compared to other fine ceramics, SiC is outstanding in its chemical stability and corrosion resistance.
The material is noted for its high hardness level, small expansion coefficient, and excellent thermal conductivity. Silicon carbide is a dynamic material as it is used as an industrial abrasive, a component in electronics manufacturing, refractory materials, deoxidizing agent for auto parts, and many more.
