Mohs scale of mineral hardness - Wikipedia

The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material.. The scale was created in 1822 by German geologist and mineralogist Friedrich Mohs; it is one of several definitions of hardness in materials science, some of which …

What Is The Hardness Of Silicon Carbide? - …
