Application prospect of synchrotron radiation SAXS in time-resolved study of dust explosion

Dust explosions are common and highly hazardous industrial accidents that occur rapidly and involve complex changes in particle structure. Traditional experimental methods struggle to capture the time-resolved information of the explosion process, limiting the in-depth study of its dynamic mechanisms. Synchrotron radiation small-angle x-ray scattering (SAXS) offers a novel method to study the microscopic dynamics of dust particles during explosions. Utilizing high-flux x-rays from synchrotron facilities, coupled with fast detectors and specialized explosive chambers, SAXS provides high temporal and spatial resolution alongside nondestructive detection capabilities. It is expected to obtain information on particle morphology changes during dust explosions. This contribution first introduces the basic characteristics and hazards of dust explosions, reviews the current research status and challenges, and then expounds on the basic principles and advantages of synchrotron radiation SAXS. Finally, the potential of this method in real-time monitoring of dust explosion characteristics and enhancing understanding of explosion mechanisms was explored.
