“…The u (α) dependence for all samples is extreme: for KNO 3 , NaNO 3 , and CsNO 3 -based samples the maximum burning rate (r b max ) at all pressures is achieved at α~0.72 ( Figure 2). In [3] for samples with KNO 3 , this is explained by the fact that during combustion in the reaction zone of the condensed phase the ratio between fuel and oxidizer due to evaporation of the plasticizer is higher than in the initial sample. In light of this, α value in the reaction zone is close to 1.…”

“…Dibutyl phthalate (DBP) plasticized (1 : 1.5) phenol-formaldehyde resin (PFR) is used as a binder for all compositions. This type of binder is used for fire-suppressing aerosolforming compositions based on KNO 3 [2,3,7]. For the technological and mechanical properties improvement, 1.5 % Teflon, and 0.5 % calcium stearate were introduced into the compositions [7].…”

“…For decades, a large number of pyrotechnic compositions (PCs) have been reported in the literature and patents, where potassium nitrate, potassium chlorate or perchlorate, strontium nitrate has been used as oxidants 6‐12 and organic polymers include phenol‐formaldehyde (PFR), melamine‐formaldehyde, polyurethane, epoxy resin etc. used as reductants 13,14,15 .…”

“…8 Ma et al designed some formulations composed of potassium nitrate, strontium nitrate and sucrose, and then the influence of strontium nitrate content on the hot aerosol fire-extinguishing agent was researched. 9 The combustion mechanism of fire-extinguishing propellants based on potassium nitrate was investigated by Denisjuk et al 10 …”
