WebJun 10, 2024 · Starink’s method, the Flynn–Wall–Ozawa method, and the Coats–Redfern method were used to evaluate the pyrolysis kinetic parameters of the samples. The results show that when the mass fraction of 5-amino-1H-tetrazole in the system is 10%, the maximum combustion temperature of the sample decreases by nearly 70 °C and the … WebOzawa-Flynn-Wall method: Ozawa, Flynn and Wall tried to rewrite Eq. This treatment has led to establishment of the following equation. $$ ln(\beta) = ln \left ( \frac{A E_a}{R} \right ) - G(\alpha) - 5.3305 - 1.052 \frac{E_a} {R \, T} \tag{9} $$ Under the isoconversion assumption, i.e. the function G(α) reaches a given value thus a constant.
