A kinetic study of non-isothermal decomposition process of anhydrous nickel nitrate under air atmosphere

Isoconversional Methodology

“…The presence of the maximum on the y( α) plots suggests that an appropriate model should be either one of the Avrami-Erofeev or the truncated SB models. The experimental values of α m and α p were determined [72] to be smaller than those expected for the Avrami-Erofeev model (Table 2.1). For this reason, further analysis was based on the truncated SB model, for which the parameters m and n were estimated via model fitting.…”

“…Figures 2.17 and 2.18 provide an example of using the y( α) and z( α) plots to identify the reaction model for the thermal decomposition of nickel nitrate in air [72]. The use of the isoconversional methods demonstrates (Fig.…”

Two decoupling methods for non-isothermal DSC results of AIBN decomposition

“…Malek method, which almost has no assumptions and approximations, can significantly reduce the scope of kinetic mechanism functions and improve the accuracy of the mechanism function (f(˛) as a differential form or G(˛) as an integral form) determination [19][20][21][22][23]. Malek method was used, herein, to explore the most probable mechanism model for the thermal decomposition of AIBN based on DSC data.…”

Reaction Kinetics for the Synthesis of Li4SiO4 by Solid State Reaction from Li2SiO3 and Li2CO3 for Tritium Breeder

“…The Malek method has been used widely to determine reaction mechanisms (reaction order, nucleation and growth, and diffusion mechanisms) [34][35][36][37]. Figure 8 shows the yðaÞ and the zðaÞ Fig.…”
