Effect of the Polyvinyl Butyral Content on the Combustion Mode of the (Ti + C) + xNi Granular Mixture

In this paper, we study the effect of polyvinyl butyral content (0–2.3%) on combustion rate and phase composition (Ti + C) xNi granular mixture, where x = 0, 5, 10, 15, 20 wt %. At an increased binder, for first time, a convective mode is discovered due to ignition surface granules with hot gaseous decomposition products butyral. This characterized by higher propagation reaction front than follows from filtration theory. The mechanism occurrence nondecomposed behind explained. According X-ray analysis data, does not change in nickel mixture includes only two phases: TiC Ni. It shown that when scaling process obtaining composite powders charge xNi, it necessary ensure implementation conductive mode.
