Structural, electrical, dielectric and optical properties of PrCrO3 ortho-chromite

, 2020
The structural, optical, electrical and dielectric properties of PrCrO3 perovskite prepared through the sol-gel method were investigated in details. Our compound was characterized by X-ray powder diffraction (XRD) at room temperature.

Petrogenetic insights from chromite in ultramafic cumulates of the Xiarihamu intrusion, northern Tibet Plateau, China

American Mineralogist, 2020
Chromite is one of the earliest crystallized minerals from mafic melts and has been used as an important “petrogenetic indicator.” Its composition may be modified by interaction with intercumulate melt and adjacent minerals.

Selective shear flocculation of chromite from chromite-serpentine mixtures

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998
Abstract In this study, shear flocculation of chromite from mixtures of chromite and serpentine was investigated. The effects of zeta potential, contact angle, stirrer speed, flocculation (stirring) time, settling time and concentration of sodium oleate, Na 2 SiO 3 and Na 2 SiF 6 were tested.

Magnesite-chromite products from high purity magnesite and chromite

Refractories, 1971
Products made from magnesite and chromite with low-impurity oxide concentrations possess better thermal factors than ordinary periclase-spinel refractories: refractoriness under load: 1700°C and above; bending strength at 1300°C 2.5–3 times greater; deformation 3–4 times; and the rate of deformation at steady-state creep is about a half.

Enriching Saranov chromites

Refractories, 1967
A new technology was developed for enriching Saranov chromites using modern methods of enrichment and an effective technological set-up yielding chromite powders of high quality for the refractories industry. The use of enriched Saranov chromite makes it possible to produce chrome-containing refractories of high resistance.
