✦ Synopsis
The concept that combustion of solid oxidant-fuel systems is governed by thermodynamically predictable oxidant dissociation pressures and measurable kinetics of oxygen evolution is shown to be consistent with the experimental results reported here. Selection criteria and a model based on this concept show that systems thus formulated necessarily exhibit an amplification of the combustion rate, i.e., an enhancement of the speed of combustion. This is due to (1) oxidant-fuel coupling or synergy associated with the familiar exponential increase in the combusion rate with temperature and (2) sequential oxidant syuergy in systems, such as Zr/C0304, BaCrO4, Fe203, containing oxidants dissociating at sequentially increasing temperatures and rates. The net effect is that of a "kinetic stepladder." These effects were experimentally confirmed and are applied in commercial practice.
