Operasjon Chromite

, 2016
Amfibielandsettingen i Inchon 15. september 1950 er kanskje det oftest benyttede eksempelet på suksessfull operasjonell manøver. General Douglas MacArthur snudde der en vanskelig situasjon for FN og de sør-koreanske styrkene i Pusan perimeteret til seier over den nord-koreanske arméen, og gjenopprettet grensen ved den 38. breddegrad i løpet av to uker.

Determination of Chromite by X-ray Fluorescence Spectrometry with Sample Preparation of a Lower-Dilution Fusion

Yankuang ceshi, 2013
Chromite analysis is dominated by chemical analysis, which is a wel-established but complicated procedure. Chromite can also be analysed by X-ray Fluorescence Spectrometry (XRF), however, a high-dilution fusion is not conducive to low content elements ...

Metamorphism on Chromite Ores from the Dobromirtsi Ultramafic Massif, Rhodope Mountains (SE Bulgaria)

Geologica Acta, 2009
Podiform chromitite bodies occur in highly serpentinized peridotites at Dobromirtsi Ultramafic Massif (Rhodope Mountains, southeastern Bulgaria). The ultramafic body is believed to represent a fragment of Palaeozoic ophiolite mantle.

Solid-State Reduction of Chromite Concentrate - Melting of Prereduced Chromite

, 1995
The solid state reduction of a chromite concentrate from Northern Greece in the temperature range 1100-1470 degrees C has been studied. The degree of reduction of chromite by graphite was found to increase with increasing temperature, time, and carbon addition.
