Using a vacuum-tight plasma jet apparatus operated below one atmosphere, the condensation of solid particles in space was experimentally simulated. Atomized reactant gases consisting of Si, O, C, and H atoms generated in the plasma flame were injected into a reactor chamber filled with Ar gas of 200 Torr, and quenched into solid particles. The formed grains had irregular shapes and their sizes were smaller than 20 nm. X-ray diffraction patterns of the condensed grains showed no sharp peaks. It was found from IR absorption spectra that the particles contained C-H, Si-O, and Si-C bonds, irrespective of their initial abundances. These characteristics of the condensates were clearly different from those expected from equilibrium calculations.
