The Mohs' hardness scale was developed in 1822 by Frederich Mohs. This scale is a chart of relative hardness of the various minerals (1 - softest to 10 - hardest). Since hardness depends upon the crystallographic direction (ultimately on the strength of the bonds between atoms in a crystal), there can be variations in hardness depending upon ...

The Hardness Value of Silicon. On the Mohs scale, which is a relative scale, silicon has a hardness of about 7. This means it will scratch more common materials like glass, quartz, steel, and titanium. Materials with a Mohs hardness above 7 like diamond, cubic boron nitride, and boron carbide can easily scratch silicon.
