Fe-substituted mullite powders for the in situ synthesis of carbon nanotubes by catalytic chemical vapor deposition [PDF]

, 2009
Powders of iron-substituted mullite were prepared by combustion and further calcination in air at different temperatures. A detailed study involving notably Mo¨ssbauer spectroscopy showed that the Fe3+ ions are distributed between the mullite phase and a
