The article considers the results of influence of inorganic fluorides and iron oxide with

different dispersion on the burning characteristics of the pyrotechnic composition based

on magnesium and sodium nitrate. It shows the laws of burning rate of the studied com-

pounds depending on the type of the additive and the degree of increase the burning rate

using different additive content. It was established that under all other equal conditions

the effect of increasing of the burning rate under high pressure is mainly caused by the

increase of the exponent in the law of burning rate. The article also shows the ability to

control the burning rate by the appending of the necessary amount of additive

Keywords:

pyrotechnic composition, fluorides of metals, ultra- and nanodispersed pow-

ders, burning rate.
