Quick Answer: Is Silicon Carbide Harder Than …

Is silicon carbide harder than diamond? Tungsten carbide is extremely hard, ranking about 9 on Mohs scale, and with a Vickers nuer of around 2600. It has a Young’s modulus of approximately 530–700 GPa, Chromium, on the Mohs scale for hardness, is the hardest metal around.

Crystals | Free Full-Text | Vickers Hardness of …

The Vickers hardness of the (111) plane of type-Ib synthetic diamond at 5-N load is about 80 GPa, which is appreciably lower than the Vickers hardness of natural type-Ia diamond (92 GPa ). This is probably the consequence of a high density of disloions and nitrogen concentration in the type-Ib synthetic diamond sample produced by the spontaneous crystallization.
