The thermal behaviors of potassium perchlorate with graphite powder we
re investigated by DTA, and the kinetic parameters of the thermal deco
mposition of potassium perchlorate with graphite powder were studied b
y dynamic TG. Graphite powder plays a catalytic role in thermal decomp
osition of potassium perchlorate. Adding graphite powder into potassiu
m perchlorate results in remarkable acceleration effect on the decompo
sition of KClO4.
