T1 SYNTHESIS OF ULTRAFINE PARTICLES OF MATERIALS IN EROSIVE LASER PLASMA IN A HIGH-PRESSURE GAS ATMOSPHERE JF High Temperature Material Processes: An International Quarterly of High-Technology Plasma Processes JO HTM YR 1997 FD 1997-12-20 VO 1 IS 4 SP 535 OP 547 AB Synthesis of ultrafine particles as a result of condensation in an erosive jet at laser vaporization of materials (metals, metal oxides, carbon) in gases (hydrogen, oxygen, helium, argon, xenon and air) at high pressures is investigated. The granulometric, phase, and chemical composition of the condensate particles is analyzed in relation to the elaboration conditions. It is found that the mean dimensions of the condensate particles increase with an increase of the ambient gas pressure. A particle nucleation and growth theory is used to describe the formation of the dispersed condensate in the erosive plasma. It is shown that the resulting particle size distribution is determined by the dependence of the cooling rate of the vapor-gas mixture on the pressure of the surrounding gas.
