In order to improve the reaction rate of pyrotechnical reagent

transition metal oxides (TMO)

Fe2O3 and CuO

were added into potassium perchlorate and potassium nitrate respectively by mixing and crystallization methods. Accelerating rate calorimeter (ARC) was used to study the catalytic behavior of TMO. Results illustrated that Fe2O3 can catalyze pyrotechnical reagent with potassium perchlorate

and the addition is better with crystallization method. The maximal reaction rate of pyrotechnical reagent with potassium perchlorate added with Fe2O3 by crystallization method is 8.10 min-1

which is 4.09 times of that without catalyst. The time to maximal rate is 8.52 min

which is lower than that without catalyst by 92.8%. It was also found that CuO can catalyze pyrotechnical reagent with potassium nitrate

and the addition is better with mixing method. The maximal reaction rate of pyrotechnical reagent with potassium nitrate added with CuO by mixing method is 7.38 min-1

which is 1.30 times of that without catalyst. The time to maximal rate is 53.55 min

which is lower than that without catalyst by 66.3%.
