    Abstract: These glass bodies are light weight porous structures such as a boules of high purity fused silica or ultra-low expansion glass. More specifically, the porous structures are supports for mirror blanks. Porous glass is made utilizing flame deposition of pure silica or doped silica in a manner similar to the production of high purity fused silica. Bubbles or seeds are formed in the glass during laydown. Several means of creating and controlling these seeds are available. The processes use incomplete combustion to create the bubbles. There are a number of different steps to create the incomplete combustion. One such step involves maintaining a short distance between the hydrolysis flame and the glass precursor.

    Abstract: Ultra-low expansion silica-titania glasses are produced by flame deposition of a mixture of vaporized octamethylcyclotetrasiloxane (OMCTS) and vaporized titanium isopropoxide (Ti-Ipox). Ti-Ipox is vaporized by nitrogen bubbled from conduit (16) into tank (12) and OMCTS is vaporized by nitrogen bubbled from conduit (14) in tank (10). Before being mixed with the Ti-Ipox, the OMCTS is dried so that its water content is less than 2 ppm and preferably less than 1 ppm. In this way, the formation of a precipitate on the glass making equipment (e.g., burners (28), distribution manifold (26), static mixer (18), joint (13), and conduits (20, 22, 24 and 30)) is avoided. Such a precipitate if allowed to form will result in premature shutdown of the glass making process and can result in undesirable variations in the composition of the silica-titania glass being produced.

    Abstract: The present invention is directed to a process for forming a preform suitable for consolidation to a glass blank for producing an optical waveguide fiber. The preform comprises a core portion and an inner cladding layer surrounding the core portion and contains SiO2 and TiO2. A portion of the TiO2 in the preform is in a crystalline form that is predominantly rutile. In addition to SiO2 and TiO2, the preform contains an additive compound that is preferentially sacrificed instead of TiO2 when the preform is consolidated. The process includes oxidizing Si and Ti containing compounds as well as a precursor of the additive compound to form SiO2, TiO2, and the additive compound. The preform containing these materials is then formed. In addition, the preform can be converted to a glass blank by consolidation of the preform.
