    Abstract: A method for forming high purity silica articles. The high purity silica articles can be particularly suitable for forming packaging such as packaging for pharmaceutical applications. The method for forming high purity silica articles can comprise, in one embodiment, (a) forming a fused quartz melt from a SiO2 raw material; (b) forming a quartz tube from the fused quartz melt; (c) treating the quartz tube with an acid composition; (d) heat treating the quartz tube subsequent to treating with the acid composition; and (e) optionally treating the quartz article with an acid composition subsequent to the heat treating operation. The method can enhance the purity of silica glass articles and products made therefrom.

    Abstract: The present invention provides a silica container for pulling single crystal, the container having a straight body portion, a curved portion, and a bottom portion, wherein an outer side of the container is made of opaque silica glass containing bubbles, and an inner side of the container is made of transparent silica glass, and a mixed silica layer in which a phase in which a crystalline silica powder is fused and a phase in which an amorphous silica powder is fused are mixed in a granular texture is provided on at least an inner surface layer portion of the straight body portion. As a result, there is provided the silica container for pulling single crystal silicon which can suppress melt surface vibration of a silicon melt in the silica container at a high temperature.

    Abstract: An optical fiber preform (10) includes an outer overclad glass tube (21) with a wall thickness (W2) and an impurity that contributes to attenuation if present in a drawn fiber core. A plurality of glass tube sections of higher purity are supported inside the outer tube to form an inner overclad tube (20) with a wall thickness (W1). The wall thickness of the outer tube is substantially greater than that of the inner tube to achieve a desired cladding to core ratio for the drawn fiber, while signal attenuation in the fiber is unaffected by the impurity in the outer tube. One or more core rod segments (18) are disposed inside the inner tube, and a plug (22) is fixed at the open lower end of the outer tube beneath a lowermost core rod segment and a lowermost section of the inner tube. The plug (22) blocks the rod segments from falling out of the inner tube, and supports the inner tube sections inside the outer tube as the preform descends into a furnace.
