What is degree of hardness?

Answer 1

The scale of mineral hardness is referred to as the Mohs scale. They run from 1 which is Talc to 10, which is diamond. The other units are 2: Gypsum, 3: Calcite, 4: Fluorite, 5: Apatite, 6: Feldspar, 7: Quartz, 8: Topaz, and 9: Corundum.

Answer 2

There is no simple answer or single unit of hardness, but there are many different scales and systems used to measure different kinds of hardness. The most familiar to most people would be the Mohs' scale. It is used to measure the hardness of stone on a non-linear scale from 1 to ten. Talc, the softest, is 1 and the hardest, diamond, is 10. It isn't linear because diamond is actually 42 times harder than talc, not 10 times.

Answer 3

The degree of hardness refers to how resistant a material is to deformation. It is typically measured using scales like the Mohs scale for minerals or the Rockwell scale for metals. Higher degree of hardness indicates greater resistance to scratching or indentation.

Answer 4

Degree of hardness refers to the Moh's scale of mineral hardness. It talks about the scratch resistance of each mineral on the scale.

Answer 5

- dGH or degree of general hardness

- dKH or German degrees of hardness

- mg/L of calcium carbonate or hydrocarbonate

Answer 6

Among some others, there are: mmol/L, ppm, mg/L, dGH, °dH, °fH, gpg, °e, °Clark

All of them measure the amount of Ca and other bivalent ions like Mg, Zn, Mn.

Answer 7

ppm
