This article investigates the burning of metal powder in flat layers when the oxidant is supplied through the open free surface. The experiments were performed in a nitrogen atmosphere with PTS titanium powder having an effective particle size of 3x10-/sup 4/m. The combustion was observed through an illumination by means of an RFK-5 motion-picture camera fitted by means of adjusting the frame frequency from 1 to 10 frames/sec. The burning speed was determined by the slow processes of infiltration and diffusion deep within the layer. The results indicate that the burning rate is substantially higher near the open surface.
