Popis: A new method was proposed for studying the kinetics of gas-dispersed systems in shock waves. The method is based on the pulsed sputtering of microscopic amounts of finely grained powder immediately before arrival of a shock wave. The method was used for investigating the oxidation of soot particles with molecular hydrogen (T = 1700–2400 K) and their vaporization (T = 4000–6000 K) in an argon atmosphere. The rates of these processes and the time dependence of the temperature of soot particles were measured. A model was proposed for characterizing the vaporization of soot.
