Definitions

  • U.S. Patent Application Serial Number 08/767,653 discloses that these and other limitations can be overcome by delivering a feedstock to an injector or burner in liquid form, atomizing the feedstock to form an aerosol containing fine droplets of the liquid feedstock, and converting the atomized liquid feedstock into soot at the combustion zone. Because the feedstock is delivered directly into the burner flame as a liquid rather than a vapor, the vapor pressure of the feedstock is no longer a limiting factor in the formation of soot for use in the manufacture of optical waveguides.
  • liquid reactants liquid feedstocks or precursors
  • FIG. 2 schematically depicts a second preferred embodiment of the system of the present invention.

Abstract

Dans cette invention, un premier liquide (30) se trouvant dans un récipient (28) est acheminé jusqu'à un brûleur (14), puis un second liquide (34) se trouvant dans un second récipient (32) est acheminé jusqu'au brûleur. Ce brûleur produit ensuite de la suie qui est déposée sous la forme de silice (36) sur un substrat.
