Abstract
Results are presented of the determination of the temperature of the surface of powders in experiments on plasmachemical synthesis of micro- and nanosize structures in the mixtures of aluminum oxide Al2O3 and palladium Pd with different palladium concentrations. The obtained estimates of surface temperature (3100–2400 K) are between the melt and boiling points at atmospheric pressure of the components of the powder mixture Al2O3 and Pd, which creates suitable conditions for the ignition of self-sustained (chain) plasmachemical reactions.
