Synthesis and EOS study of orthorhombic (Fe,Ni)(C,Si) and its importance as a possible constituent of Earth's core
Bishnupada Ghosh, Mrinmay Sahu, Pinku Saha +2
We have synthesized an orthorhombic phase of nickel and silicon doped FeC at high-pressure and high temperature using a laser-heated diamond anvil cell. The synthesized…
