TLDR
In this article, structural defects were introduced into the potassium bromate (PB) lattice in the form of SO2− 4 and Cl− ions in the process of crystal growth.Abstract:
Structural defects were introduced into the potassium bromate (PB) lattice in the form of SO2− 4 and Cl− ions in the process of crystal growth. It was assumed that these doped crystals PB(Cl−) and PB(SO2− 4) are composed of a two phase system, one being the perfect PB lattice and the other distorted regions due to induced defects. Isothermal decomposition of doped and normal PB samples was carried out gasometrically between the temperature range 653–663 K. The α-t plots reveal that the process occurs through initial gas evolution, acceleratory and decay stages. It also confirmed that doping enhances the rate of the reaction, the effect being more pronounced in the case of PB(SO2− 4). The data are found to be well fitted to the Prout-Tompkins and Avrami-Erofe'ev mechanisms.read more

Influence of trivalent ion dopants on the thermal decomposition kinetics of potassium bromate
TL;DR: In this article, the isothermal decomposition of potassium bromate (KBrO 3 ) has been studied as a function of concentration of dopants, phosphate and aluminium by thermogravimetry (TG) in the temperatures range 668-683 K. The results showed that the decomposition was best described by contracting cylinder equation.

Role of Point Defects in the Thermal Decomposition of Ammonium Perchlorate
J. N. Maycock,V. R. Pai Verneker +1 more
TL;DR: The thermal decomposition of ammonium perchlorate has usually been described in terms of chemical reactions with the point defect structure of the solid ignored as mentioned in this paper, however, the authors of this paper have shown that charge carriers play a significant role in the decomposition.
