Calcium carbonate is not a particularly hard mineral, with pure calcite falling at about 3 on the Mohs scale of 1 (talc) to 10 (diamond). Silica impurities in the line can raise the hardness of some ground calcium carbonates to a Mohs value of 4. Calcium carbonate is subject to attack by acidic environments, which has led.

Mohs scale of mineral hardness - Wikipedia

The Mohs scale of mineral hardness 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.
