Role of γ-irradiation and Ba2+ doping on the isothermal decomposition of caesium bromate

Abstract

Role of },-irradiation and Ba 2+ doping on the isothermal decomposition of caesium bromate has been investigated gasometrieally. It is seen that decomposition proceeds in a molten/semi-molten state presumably due to formation of an eutectic between the product bromide and the host material, i.e., bromate. The process exhibits stages: (i) initial gas evolution (initial puff) (ii) short aeceleratoty and (iii) long decay. The data are analysed in the light of theories of different kinetic models like Prout-Tompkins, Avrami-Erofeev and explore that irradiation as well as doping enhance decomposition.

Effect of Doping and Irradiation on the Decomposition of NaBrO3: A Kinetic Study

“…According to Bhatta et al [10][11][12][13] doping as well as irradiation facilitate the decomposition of caesium bromate and the data are well fitted to various kinetic equations like Prout-Tompkins, Avrami-Erofeyev and contracting square. Influence of cation (Al 3+ ) and anion (PO4") doping as well as y-irradiation on the isothermal decomposition of barium bromate has been studied by Mohanty et al [14,15].…”
