  This study investigates the impact of resonant acoustic powder mixing on the
delay time of the W-KClO4-BaCrO4 (WKB) mixture and its potential implications
for powder and material synthesis. Through thermal analysis, an inverse linear
relationship was found between thermal conductivity and delay time, allowing us
to use thermal conductivity as a reliable proxy for the delay time. By
comparing the thermal conductivity of WKB mixtures mixed manually and using
acoustic powder mixer, we found that acoustic powder mixing resulted in minimal
deviations in thermal conductivity, proving more uniform mixing. Furthermore,
DSC analysis and Sestak-Berggren modeling demonstrated consistent reaction
dynamics with a constant activation energy as the reaction progressed in
samples mixed using acoustic waves. These findings underscore the critical role
of uniform powder mixing in enhancing the thermodynamic quality of the WKB
mixture and emphasize the importance of developing novel methods for powder and
material synthesis.
