Abstract

This article is devoted to the study of the fire-hazardous properties of pyrotechnic products based on powders of aluminum-magnesium alloys with a nitrate-containing oxidizer (NaNO₃). The article presents thermodynamic calculations of temperature and composition of combustion products of these products depending on the ratio of components and the state of the environment. The obtained results make it possible to determine possible fire-hazardous situations at the stage of development and design of pyrotechnic products based on them. Such information helps prevent possible fires and accidents when storing and launching pyrotechnic products.
