“…As is known [1], combustion synthesis of cermets from powders is accompanied by the release of impurity gases present in starting powders. The influence of gas evolution on the burning velocity of SHS reactions found its explanation in terms of the convective-conductive model (CCM) of combustion [2]. A weaker retarding action of the impurity gases present in Ti and C particles on combustion of granulated T-C-based mixtures was reported by Vorotilo et al (see [3] and references in).…”

For combustion of powdered and granulated 5Ti + 3Si mixtures in a cylindrical channel, we explored the retarding action of impurity gases released from Ti particles of varied particle size. Green mixtures for combustion experiments were prepared from: (a) coarse and fine Si powders and (b) Ti powders of the following fractions: <169 μm, <54 μm, <40 μm, 40-80 μm, 90-125 μm, and 125-200 μm. The behavior of burning velocity in powdered mixtures was rationalized in terms of the CCM theory, while that of granulated ones turned to obey the classical theory for flame propagation in condensed disperse systems. Our results may turn interesting to those engaged in R & D of silicide powders.
