    Abstract
  • Fe3C (cementite) is a widely used material with excellent mechanical and magnetic properties; therefore the preparation method of Fe3C has been widely concerned. In this paper, dense and high-purity bulk Fe3C samples were prepared based on the solid-phase reaction of iron and carbon under high temperature and high pressure, and the influence of raw material type, particle size, sintering temperature, pressure, and holding time are investigated for the sintered samples. It shows that the densest samples were produced under the sintering pressure and temperature of 4 GPa and 1000 ̊C when the Fe and graphite particles were 9 $ {\text{μ}}{\rm{m}}$ and 1.3 $ {\text{μ}}{\rm{m}}$ respectively.
