THE DUST-GAS
FIREBALL AS A SPECIAL FORMOF THE ELECTRIC EROSIVE DISCHARGE AFTERGLOW
Abstract.
Main results of researches of the electric erosive discharge afterglow plasma, of the fireballs being formed by this plasma and having some particular but deep similarities to the ball lightning
are given. The analysis of our results and results of some other authors has allowed to specify the nature of radiation and stability of the shape for a dust-gas chemical fireball, to make series of assumptions concerning the mechanism of these properties. The experimental results and considerations of the given work can be interesting for physics of plasma with different kinds of condensed state, for an ascertainment of the chemiluminescence mechanism of the flame, as well as for a bead lightning understanding and for improvement of ball lightning laboratory analogues .

A new type of pulse high voltage electric discharge through a thin conducting layer on the surface of glass plate has been investigated. The afterglow plasma of this discharge forms quasi-spherical object with lifetime about 0.20.3 s. Electric properties of the objects were studied by electric probe method. Measurements of plasma radiation spectra kinetics at visible, near ultraviolet and near infrared spectral ranges have been carried out with resolution about 1 A. Comparative analysis of the physical properties of the plasmoids appearing in this discharges and of ones generated via thin metal wires burning is given. Possible mechanism of the plasma metastability are discussed.
