With rising temperature, the formation of hematite (Fe2O3) increased at the expense of the silicate mineral. Illite; Thermal decomposition; Mössbauer Spectroscopy ...

The results of physico-chemical and mineralogical characterizations of laterite and mine tailings showed that: (i) laterites are composed of quartz (SiO2), kaolinite (Al2Si2O5 (OH)4), hematite (Fe2O3) ...

Perseverance has uncovered unusual, basalt-rich Martian spherules that likely formed in violent explosions—either from ...

Temperature, time and cooling regimes were established for transformation of soft hematite and iron glance into maghemite in an oxidizing atmosphere; hematite structure seems to aid in retaining ...

The team hopes to create Bose-Einstein condensates of high-energy magnons using iron ore hematite particles at room temperature, unlike the ultra-cooling demands of quantum research today.

The capping agent plays a critical function in anisotropic crystal growth to induce polyhedral morphology of a nanocrystal. Uniform and single-crystalline α-Fe2O3 polyhedral nanoparticles in the ...

Water adsorption and dissociation on undoped and Ti-doped hematite thin films were investigated using near-ambient pressure photoemission and DFT calculations. A fine understanding of doping effects ...

This paper aims at reviewing literature on the occurrence of phosphorus in iron ores from the mines around the world. The review extends to the phosphorus removal processes of this mineral to meet the ...
