Abstract

Intisari Telah dilakukan studi simulasi reaksi dan analisis Differensial Thermal Analysis (DTA) untuk pembentukan ferrite dengan imbuhan NiO, ZnO dan CuO, serta variasi substitusi NiO dengan MnO. Material yang digunakan adalah powder teknis dengan komposisi NiO (2−X) MnOX CuO0.2ZnO0.6Fe2O3. Analisis dilakukan dengan DTA buatan LIPI dan simulasi dilakukan dengan data base HSC 5.0. Simulasi Gibs Energy menunjukkan bahwa semua reaksi dapat berlangsung sejak suhu kamar. Namun demikian, kalsinasi terjadi pada suhu 200-300 • C, dan berakhir pada suhu dibawah 450 • C. Substitusi NiO ke MnO menurunkan kebutuhan energi untuk reaksi. Substitusi NiO ke MnO menunjukkan kecenderungan untuk menurunkan suhu kalsinasi. 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) MnOX CuO0.2ZnO0.6Fe2O3. 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 200-300 • C, and was finalized at temperature just below 450 • C. Substitution of NiO with MnO decrease the energy consumption for reaction. Substitution of NiO with MnO showed the tendency of calcinations temperature reduction.
