  • Method for making a preform doped with a metal oxide
    Patent number: 5203897
    Abstract: An improved method for making preforms by vapor deposition soot laydown processes is provided wherein an oxidizing atmosphere is used during at least part of the laydown process, e.g., during the laydown of the center portion of the preform. The use of such an atmosphere has been found to result in enhanced dopant capture, reduced axial trends, and an overall stabilization of the laydown process. A method for selecting burner flows which optimize the laydown process is also provided.
