Sažetak
This article discusses the calculation of the apparent activation energy (CuМоO4 + C) on the DTA (Differential Thermal Analysis) curve, to study and optimize the time-temperature synthesis mode, in particular, the activation energy. Activation energy allows us to investigate the elementary act of chemical interaction. Thus, we propose to use this method to calculate the interaction of Eact (CuМоO4 + C) in the solid phase of hardening occurring during synthesis. These results allow us to trace how much energy is expended to start the reaction.
