The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.

The Knoop hardness of 4H and 6H single crystals of silicon carbide (SiC) was determined at room temperature. X-ray diffraction techniques confirmed the crystal structure and orientation of each polytype verifying that both discs had the six-fold symmetry expected for a hexagonal crystal and that the c-axis was oriented approximately perpendicular to disc faces.

Abstract Recent data on crystal chemistry and polytypes on silicon carbide are reviewed, and brief discussions are given on the origin of SiC polytypes, i.e. the thermal stability of basic polytypes such as 2H, 3C, 4H, 15R and 6H, the effects of foreign atoms incorporated in the lattice on the stability of the basic polytypes, and the stability of long-period polytypes.
Silicon carbide''s hardness and rigidity make it a desirable mirror material for astronomical work, The Knoop hardness of moissanite is 3000. This puts the Mohs hardness of moissanite around 8.5–9.25—as stated here, 9 1/4 may not be recognized, but 8.5–9]
