Stable dusty structures —liquid and solid Coulomb crystals of SiO2 aerosol— were found to form upon thermally initiated chain combustion of dichlorosilane, SiH2Cl2, in oxygen in rf plasma at reduced pressure. The addition of Cr(CO)6 to combustible mixtures was found to improve the stability of dusty structures and uniformity of their size distribution.
