Overview of nano silicon carbide:

Silicon carbide (SiC) is a hard compound containing silicon and carbon. A semiconductor that occurs in nature in the form of the extremely rare mineral montmorillonite, but has been produced in large quantities in powder and crystal form and used as an abrasive since 1893. Silicon carbide particles can be sintered together to form very hard ceramics that are widely used in applications that require high durability, such as automotive brakes, automotive clutches, and ceramic plates in bulletproof backplates. Large single crystals of silicon carbide can be grown by the Lely method, and they can be cut into gemstones called synthetic mozurites.

Before the invention of boron carbide in 1929, silicon carbide was the hardest known synthetic material. It has a Morse hardness of 9, which is close to diamond. In addition to hardness, silicon carbide crystals have fracture properties that make them useful for grinding wheels as well as sandpaper and cloth products. Its high thermal conductivity, combined with its high temperature strength, low thermal expansion and chemical resistance, make silicon carbide valuable in the manufacture of high temperature bricks and other refractory materials. It is also classified as a semiconductor with conductivity between metal and insulating material. The combination of this property and its thermal properties makes SiC a promising replacement for traditional semiconductors such as silicon in high temperature applications.

SiC nanomaterials have high forbidden band width,high critical breakdown electric field and thermal conductivity,small dielectric constant and high electron saturation mobility,as well as strong radiation resistance and good mechanical properties.Ideal material for electronic and optoelectronic devices with high frequency,high power,low energy consumption,high temperature resistance and radiation resistance devices.

Is silicon carbide harder than steel?

Silicon carbide ceramics are more than four times harder than stainless steel.

Is silicon carbide stronger than diamond?

Silicon carbide has a Mohs hardness of 9.5, second only to the hardest diamond in the world.
