The Material Structure and Properties of Silicon Carbide Sintered at Atmospheric Pressure
Among modern high-tech refractory raw materials such as C, N, and B—non-oxide compounds—pressureless-sintered silicon carbide is widely used and economically viable; it can be considered a type of carborundum or refractory abrasive sand. Pure silicon carbide is a colorless, transparent crystal. So what exactly are the material structure and properties of silicon carbide? Let’s take a closer look at pressureless-sintered silicon carbide below!

Main Components and Applications of Atmospheric-Pressure Sintered Silicon Carbide
Pressureless-sintered silicon carbide is a nonmetallic carbide in which silicon and carbon are bonded via covalent bonds. Its hardness ranks second only to that of diamond and boron carbide. Its chemical formula is SiC. It appears as colorless crystals, but turns blue or black when its surface is oxidized or contains impurities.

Their performance is compared extensively in many books; the biggest drawback of silicon carbide is that it’s extremely difficult to sinter! Silicon nitride is relatively expensive! As for zirconia, its phase-transformation toughening effect is unstable and exhibits time-dependent behavior. Once this issue is overcome, not only zirconia—but the entire ceramics field—could see a breakthrough!
