Abstract

Study on simulation of reaction and Differensial Thermal Analysis (DTA) of ferrite formation with addition of NiO, ZnO and CuO, including NiO substitution variation with MnO has been done. The materil utilized in this experiment was technical powder material with composition of NiO_(2-x)MnO_xCuO_0.2ZnO_0.6Fe₂O₃. Thermal analysis was carried out using DTA apparatus made in LIPI and simulation was conducted using database from HSC Chemistry 5.0 software. Simulation of Free Gibbs Energy showed that all reaction can be undergo at room temperature. However, calcination was happened at temperature of 200-300⁰ C, and was finalized at temperature just below 450⁰ C. Substitution of NiO with MnO decrease the energy consumption for reaction. Substitution of NiO with MnO showed the tendency of calcinations temperature reduction.
