high purity nitrogen atmosphere at different heating rates (3, 6, 9, 12 K</span><span style=\"font-family:Verdana;\">/</span><span><span style=\"font-family:Verdana;\">min). The thermal decomposition
mechanism of PSI was determined by Coats-Redfern method. The kinetic parameters

factor (</span><i><span style=\"font-family:Verdana;\">A</span></i><span style=\"font-family:Verdana;\">) and reaction order (</span><i><span style=\"font-family:Verdana;\">n</span></i><span style=\"font-family:Verdana;\">) were calculated by Flynn-Wall-Ozawa
