  • Ball Milling Method For Fe2o3

A Simple and Low‐Cost Method to Synthesize Cr‐Doped α

Chromium‐doped α‐Fe 2 O 3 samples are successfully synthesized by using a ball‐milling‐assisted rheological phase method combined with heat treatment The electronic properties of undoped α‐Fe 2 O 3 and 4 0 at % Cr‐doped α‐Fe 2 O 3 are investigated by first‐principles calculations The calculation results show that Cr doping can reduce the band gap and impurity levels that
