This was not measured bu it is estimated to be approx. 3,8.
I don't found the Mohs hardness of plutonium but: - the Brinell hardness is 242 at r.m. - the Vickers hardness is 255 at r.m. After a hardness conversion chart an equivalent Mohs hardness may be 3,7.
Plutonium is a silvery metal.- Vickers hardness: 255 - Brinell hardness: 242 - Mohs hardness: cca. 3,7
This scale was proposed by the Austrian geologist Friderich Mohs.
It's called the Ore
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
Nickel has a hardness of 4 on the Mohs scale.
The hardness is 3-4 on Mohs scale.
Topaz is number 8 on the Mohs scale.
The Mohs scale compares the hardness of an object or substance.
The softest material in the mohs scale is talc
Azurite has a hardness of 3.5 to 4 on the Mohs hardness scale.
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
