Abstract The iron-base alloy catalyst for synthesis of high-grade diamond monocrystal contains Fe, Ni, Mn, Co, Cu and graphite and has a Fe content of 50-76%. The catalyst is prepared through the processes of mixing powder of the components, cold pressing to form, low temperature sintering in sintering furnace, shaping and surface finishing. The preparation process has high finished product rate and the catalyst can be used to produce high-grade diamond with high strength and large size at low cost.
