Magnetite - an overview ScienceDirect Topics

Measuring the magnetite solubility has proven to be more difficult than that of other oxides, such as NiO, due to the reductive dissolution of magnetite from Fe (III) to Fe (II) [32]. Thus the reduction potential of the entire system plays an important role in magnetite solubility.

Strain gradient plasticity to study hardness behavior

The hardness of a material is generally affected by the indentation size effect. The strain gradient plasticity (SGP) theory is largely used to study this load dependence because it links the hardness to the intrinsic properties of the material. However, the characteristic scale-length is linked to the macrohardness, impeding any sound discussion.

2013-9-16  Hardness. Hardness is determined by scratching the mineral with a mineral or substance of known hardness. Hardness is a relative scale, thus to determine a mineral's hardness, you must determine that a substance with a hardness greater than the mineral does indeed scratch the unknown mineral, and that the unknown mineral scratches a known mineral of lesser hardness.
