    Abstract: A system for delivering a liquid reactant (2) at high flow rates to an oxidation/flame hydrolysis glass soot deposition site (10). A first liquid only reactant (2) is delivered (7,4) to a vaporization chamber (1) to form a thin film and mixed with oxygen (20) after vaporization. Additional vaporized reactants (30) are thereafter mixed (11) with the vaporized first liquid (1) prior to delivery to an oxidation/flame hydrolysis burner (10) to form a glass soot outer cladding layer on a soot preform. The soot preform is subsequently fused to form a high quality glass blank for drawing into optical fiber.

    Abstract: Reactant vapours, for optical fibre preform prodn., are provided by (a) flowing a liq. reactant onto the upper portion of a surface inclined w.r.t. the horizontal at an angle sufficient to form a downflowing film of thickness less than that which would support a bubble during boiling; and (b) heating the surface to above the liq. boiling temp. to convert the liq. reactant to a vapour. Also claimed is a vaporiser for vaporising reactant materials in optical fibre preform prodn.

    Abstract: This invention relates to the production of high purity fused silica glass through oxidation and/or flame hydrolysis of a halide-free, organosilicon-R compound in vapor form having the following properties: (a) producing a gas stream of a halide-free silicon-containing compound in vapor form capable of being converted through thermal decomposition with oxidation or flame hydrolysis to SiO2; (b) passing said gas stream into the flame of a combustion burner to form amorphous particles of fused SiO2; (c) depositing said amorphous particles onto a support; and (d) either essentially simultaneously with said deposition or subsequently thereto consolidating said deposit of amorphous particles into a virtually nonporous body; the improvement comprising utilizing a halide-free, organosilicon-R compound in vapor form having the following properties: (1) a Si-R bond dissociation energy that is no higher than the dissociation energy of the Si-O bond; (2) a boiling point no higher than 350 DEG C; and (3) which, upon pyrolysis and/or hydrolysis, will produce decomposition products beside SiO2 which are deemed to be environmentally safe or the emissions are below acceptable governmental standards.
