Comparison of hardness of boron carbide and other substances
Comparison with diamond hardness:
Diamond is the hardest substance in nature, with a Mohs hardness of 10.
Although the hardness of boron carbide is also very high, it is slightly lower than diamond.
Comparison with cubic boron nitride hardness:
Cubic boron nitride is a synthetic super-hard material whose hardness is second only to diamond.
Boron carbide is similar in hardness to cubic boron nitride, but cubic boron nitride is generally considered harder.
Hardness comparison with other materials such as silicon carbide:
Silicon carbide is also a relatively hard material and is often used to make abrasives and cutting tools.
Boron carbide is significantly harder than silicon carbide.
