Investigation on formulation optimization of novel dispersion charge based on B and BaCrO₄ system

Abstract The application of dispersion charges in central gas-type dispersion devices is restricted by suboptimal energy density optimization and inadequate reaction rate modulation mechanisms, leading to problems such as poor distribution uniformity and a small dispersion area. This study addresses these limitations through thermodynamic performance characterization and combustion product analysis, culminating in the development of a novel diffusion material formulation based on boron-based composite fuel (20 wt%) and FKM. By employing oxidation equilibrium principles and secondary reaction excitation design, the optimized system achieves an energy density of approximately 6.9×10 4 J/g. The porous structural features observed in combustion products substantiate sufficient gas emission capacity during combustion. Experimental results demonstrate exceptional thermal stability and environmental adaptability of the material system. This advancement provides a viable material solution for improving the dispersion efficiency of the dispersion device, especially helping to address the issues of uniform energy release and combustion consistency.
