Abstract (en)
[origin: WO0192172A1] A method of vaporizing a liquid TiO2 precursor utilized in making a titania-doped fused silica preform includes passing the liquid TiO2 precursor through a packed-bed vaporizer with a carrier gas under conditions sufficient to vaporize the TiO2 precursor without substantial thermal degradation thereof. Further, the method includes commingling the vaporized TiO2 precursor with a vaporized SiO2 precursor and delivering the mixture to a vapor utilization site to form the preform. In one embodiment of the present invention, liquid TiO2 and SiO2 precursors are contemporaneously vaporized in the vaporizer and delivered to the vaporization utilization site to form the preform.
