The effect of doping on the thermal decomposition of strontium bromate
摘要:
The thermal decomposition of strontium bromate doped with KBrO3, Mg(BrO3)(2), Al(BrO3)(3) and KBr (10(-4) to 10(-1) M), was studied by dynamic thermogravimetry and the kinetic parameters were computed using the Coats-Redfern and Horowitz-Metzger equations. Doping enhances the decomposition and decreases the energy of activation in samples doped with Al(BrO3)(3) and KBr, whereas KBrO3 and Mg(BrO3)(2) increase the thermal stability of Sr(BrO3)(2).
