Chemical activity of dispersed particles of potassium compounds in a pyrotechnic flame

Modern developments of aerosol-generating compounds are associated with increased fire extinguishing efficiency and decreased temperature and chemical activity of twophase combustion product flow. When burning these  compounds in special generators, it is important to release particles as small as possible into the environment. The concentration of these particles must be commensurate with the concentration of active flame particles in the combustible material being extinguished. The structure of particles in pyrotechnic flames has been studied and the possibility of producing particles with reduced corrosion resistance has been demonstrated. A mechanism for the  interaction between reacting particles and potassium iodide crystals has also been proposed.
