Parra thermal oxidation oxidative conditions CC-BY The kinetics of the thermal oxidation of white metal and Cu2S have been studied by thermogravimetric analysis (TG), which was carried out under atmospheric oxidative conditions (O2 100%) with heating rates of 5, 10, 15 and 20 °C min−1. Each experiment was performed three times, the indicated values being the average of the three experiments. The experimental data were evaluated using isoconversional models based on the Arrhenius equation. The models are constructed using first-order mechanisms in the reactions and therefore, since most of them present adequate regression coefficients, it can be verified that order 1 is the most predominant order among the reactions found. In addition, the Kissinger–Akahira–Sunose model, which has the highest regression coefficient, is considered to be the most optimal. Similar behavior was recorded between Cu2S and white metal, as well as a similar regular increase in the apparent activation energy (Ea) of 10–30 kJ mol−1 for both materials. 2023-09-18T04:53:47Z 2023-09-18T04:53:47Z 2023 Book https://link.springer.com/article/10.1007/s11085-023-10169-z https://dlib.phenikaa-uni.edu.vn/handle/PNK/9071 en application/pdf Springer |
