Mohs scale of mineral hardness Wikipedia

The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1822 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness


Barium an overview ScienceDirect Topics

Barium and strontium Sulphate-Scale deposition is usually the result of two different brines co-mingling: one-brine rich in sulphate ions and the other rich in alkaline earth ions. When this happens, the solubility product of the mineral sulphate is exceeded and the water becomes supersaturated. This process is generally responsible for the formation of barium and strontium sulphates scales:

Mineral Hardness Britannica

Mineral Mineral Hardness: Hardness (H) is the resistance of a mineral to scratching. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool.
