FeNi-Ceramics (Fe3W3C, Fe6W6C) composite powder was synthesized by carbothermal reduction of Fe2O3 -WO3 -Ni mixture under argon gas atmosphere at 1200oC temperature. The standard Gibbs energy minimization method was used to calculate the equilibrium composition of the reacting species. Effects of synthesis milling time of precursors on the FeNiCeramics conversion were investigated. The resulted product phases and morphologies were identified using XRD and SEM methods. The synthesized products showed composite of ceramic (Fe3W3C, Fe6W6C) and iron-nickel alloy (FeNi) phases.
