Method of making titania-doped fused silica.

摘要

Disclosed is a method of production of high purity fused silica glass doped with titania through oxidation or flame hydrolysis of a gaseous mixture and containing rutile crystals comprising a vaporizable, silicon-containing compound and a vaporizable titanium compound. Titanium isopropoxide, titanium ethoxide, titanium-2-ethylhexyloxide, titanium cyclopentyloxide, and a titanium amide, or a combination thereof, constitute the operable halide-free titanium-containing compounds. In particular is disclosed such a method for making optical waveguide fibers.
