To improve the thermal properties of thermite safely and stably,
electrostatic spraying was used to prepare the Al/MoO3 thermite. The
Al/MoO3 thermites were detected and characterized by scanning electron
microscopy (SEM) and X-ray diffraction (XRD), and thermal decomposition
experiments were carried out by differential scanning calorimetry (DSC).
The heat release of the Al/MoO3 thermite prepared by the electrostatic
spray (1044 J·g-1) is significantly higher than that of the thermite
prepared by the ultrasonic (692 J·g-1), which is due to more uniform
dispersion between Al and MoO3. The initial reaction temperature and
activation energy (Ea) of the former keep it steady. Electrostatic spray
ensures the safety and stability of the Al/MoO3 thermite. This study
provides a new idea for safely and stably improving the thermal
properties of thermite by enhancing surface homogenization, which is of
great significance for practical applications.
