Abstract
Blast-powder interaction forms an aerosol, which could ignite, affecting production and distribution of fallout products. Full-scale experiments are challenging. Electrostatic discharges (ESD) above powders placed in a cavity serve to generate lab-scale shocks and plasma. Spherical and irregular particles of Ti–B nanocomposites were lifted by ESD. More particles are lifted and ignited by ESD with a higher voltage and when electrodes were located closer to the cavity. Spherical powders were lifted more efficiently than irregular powders. Ignited spherical particles were brighter than irregular powders. Particles lifted nearly instantly traveled at ∼100 m/s. Particles lifted later moved at lower velocities.
