The reduction of chromite in the presence of silica flux ...

The mechanism and kinetics of the carbothermic reduction of chromite was studied at 1300–1500 °C in the presence of silica. Thermogravimetry, X-ray diffraction analysis, EDAX were the main tools used. Some tests were also conducted without silica addition for comparison. Silica affected the reduction at and above 1400 °C.
