    Abstract: Provided is a manufacturing method for an optical fiber preform of which the core is doped with a rare earth element. The method includes: depositing glass particles within a silica tube by the modified chemical vapor deposition method, the glass particles mainly consisting of silicon dioxide; adding the rare earth element and aluminum to the glass particles within the silica tube by the solution doping method; heating the silica tube while flowing a phosphorous-containing gas into the silica tube to sinter the glass particles within the silica tube while adding the phosphorous; and heating and collapsing the silica tube to which the rare earth element, the aluminum, and the phosphorous are added.

    Abstract: The method and apparatus for producing liquid silicon of high purity and for casting silicon. Hydrogen and a hydrogenated silane in gaseous state are mixed, preferably with a source of a small amount of oxygen, in a heated chamber producing the liquid silicon, with the exhaust gases bubbling out of the melt under a baffle. The chamber for the melt of liquid silicon preferably is lined with silicon dioxide. The liquid silicon may be used in making high purity vitreous silica and may be used in making castings of silicon. In making castings, the liquid silicon is accumulated in a second chamber and is periodically drawn from the second chamber into a third chamber which contains the mold for the casting.

    Abstract: A method is provided for producing high purity oxide products of phosphorus and silicon such as, for example, a P2O5 and SiO2 glass wherein a silicon alkoxide is directly reacted with phosphorous acid, phosphoric acid, phosphorus pentoxide, or mixtures thereof, in the absence of any addition of a separate hydrolysis catalyst to produce a single phase solution reaction product and this reaction product with water is converted to a two-phase system, which two-phase system is removed of its free liquid components and the residue is then thermally decomposed to produce a product of phosphorus and silicon. This oxide product may be converted to a substantially unitary shape by conventional melting techniques or by conventional sintering techniques. The product may be used as an additive in conventional glass melting operations to supply at least a portion, and preferably all, of the P2O5 and/or silica requirements of the batch or the product may be compacted and suitably fired into a substantially unitary body, which body is an excellent target in sputtering applications for forming films on semiconductive materials such as, for example, silicon chips.
