Structures of the particles of the condensed dispersed phase in solid fuelcombustion products plasma

The results of experimental investigations of a type of dusty plasma which has been least studied-the plasma of solid fuel combustion products-were pr esented. Experiments to determine the parameters of the plasma of the combu stion products of synthetic solid fuels with various compositions together with simultaneous diagnostics of the degree of ordering of the structures o f the particles of the dispersed condensed phase were performed. The measur ements showed that the charge composition of the plasma of the solid fuels combustion products depends strongly on the easily ionized alkali-metal imp urities which are always present in synthetic fuel in one or another amount . An ordered arrangement of the particles of a condensed dispersed phase in structures that form in a boundary region between the high-temperature and condensation zones was observed for samples of aluminum-coated solid fuels with a low content of alkali-metal impurities.
