Abstract
We study experimentally and theoretically the threshold of discharge ignition from conducting particles in a uniform electric field in air as a function of the particle size and shape. It is established that the threshold field increases with decreasing sizes of the particles with a given shape in the entire considered size range. As a result, for particles that are smaller than the critical value, the threshold field exceeds the breakdown value for air. It is found that for each given size of the particles there exists a minimum threshold field, such that the discharge from the particles with this (or smaller) size cannot be ignited in a lower-intensity field regardless of the particle shape. The dependences of the minimum threshold field and the corresponding degree of elongation of the particles on their longitudinal size are determined.
