Abstract
Thermogravimetric analysis method was used to study the decomposition of MnCO3 in the process of MnZn ferrite preparation. The effects of different heating rate (5, 10, 20, 30 and 40 K· min-1) on the initial temperature and terminative temperature of the manganese carbonate decomposition were investigated. The Flynn-Wall-Ozawa method and Kissinger-Akahira-Sunose method were used to calculate the decomposition activation energy of manganese carbonate. The results show that the terminative temperature of manganese carbonate decomposition will increase with increasing of heating rate. The decomposition activation energy of manganese carbonate in the process of MnZn ferrite preparation calculated by FWO and KAS methods were 67.94kJ·mo l-1 and 64.31kJ·mo l-1, respectively. The decomposition activation energy of manganese carbonate in the process of MnZn ferrite preparation is lower than in another two systems.
