Abstract
A cation-excess (Ni,Mn) ferrite Ni0.52Mn0.51Fe2.05O4.0 with a single phase was synthesized by heating the mixture of corresponding metal salts and oxide in 5% O2/75% CO2/20% N2 gas mixture for 18h at 1100C. It could be thermochemically activated to form a cation-excess ferrite Ni0.52(1+δ)Fe2.05(1+δ)O4.0 in N2 gas at elevated temperature : The (value was 0.031 at 1100C. The activated (Ni,Mn) ferrite was reacted with water to form H2 gas at 700C. The process was reversible and could be carried out repeatedly.
