The time of setting of a stationary charge of particles of copper and tantalum, heated up to the melting temperature due to the electric exchange with a condensed dispersion phase of its own oxide, is determined. It is also shown that, for every time moment, the falling metallic particle can be considered as the one having aquasistationary electric charge, due to the non-stationary heat exchange with the surrounding. Experimental data on the charge of copper particles and its cooling characteristics are presented.
