Results are reported for a study of the condensation of a number of solids that are likely candidates for dust formed in astronomical environments. The condensate materials were produced by vaporizing a portion of a solid target of chosen composition by a laser pulse in an atmosphere of H2, O2, or Ar at 1 atm pressure. The systems studied include olivine, pyroxene, Fe-Ni alloy, Al2O3, carbon, CaCO3, SiC, Au-olivine powders, and Au-Al2O3 powders. Possible relations among the sizes, chainlike structures, and chemistries of the condensates and of grains formed in astronomical systems are investigated. The results indicate that the laser evaporation technique is useful for providing a wide variety of grain systems that are analogous to astronomical grain systems and that the grain materials produced are useful for spectral studies of materials believed to exist in astronomical environments, both as single materials and as multicomponent grain systems
