A PROCESS FOR PRODUCTION OF MIXED CARBIDE OF SILICON AND IRON (SIC-FE3C) FROM FLY ASH

摘要

A process for production of mixed carbide of silicon ana iron (SiC- Fe3C) from fly ash wnich comprises heating a mixture of fly ash and carbon in an electrically conducting crucible that forms the anode employing carbon cathode and argon as plasmagen gas in a plasma reactor operating in extended arc mode at temperature 1600-2200°C in a time of 10-30 min and recovering SiC-Fe3C by conventional leaching methods.
