ABSTRACT:
A new method for the manufacture of glass films on substrates involves the flame reaction of an aerosol comprised of droplets of a solution containing all the precursors for the glass. A solution containing the precursors for all oxide components is atomized, and the resulting droplets are reacted in a flame to form spherical glass particles which are deposited on a heated substrate. By moving the substrate through the flame, a homogeneous deposit is achieved. Subsequent heat treatment in a furnace sinters the porous particle layer into a clear glass. The method has been successfully employed for the formation of sodium borosilicate glass films on silicon substrates and rare earth-doped multicomponent glass films for active devices.
