| Abstract: |
The effects of titanium powder morphology and size (sponge, rolled porous, fused, spherical; particle size ranging from several 10 to several hundred micrometers) on burning rate and the characteristics of titanium agglomeration during the combustion of composite propellant containing AP, Ti and an active polymer binder at a ratio of 60/20/20 were investigated with use of sampling techniques. The goal was to optimize propellant composition in order to reduce agglomeration retaining the maximal possible titanium content in the propellant, in relation to the idea of developing a pyrotechnic generator of finely dispersed titanium dioxide. Detailed data on the morphology of sampled condensed combustion product particulate matter, their particle size and elemental composition assessed by EDS are presented. It is shown that burning rate, the mass and size of agglomerates are essentially dependent on the morphology and size of initial titanium. It has been determined that the optimal metallic fuel for the formulated goal is spherical titanium with particles smaller than 36 μm which is minimal among the studied ones. The results of EDS allow us to assume that the agglomerates burning in the air are completely transformed into the oxide, which confirms the potential possibility to develop a pyrotechnic generator of TiO2.
