    摘要: The present invention is a method for producing a silica container arranged with a silica substrate having a rotational symmetry, wherein the method comprises: a step of forming a preliminarily molded article having a prescribed shape by feeding a powdered substrate's raw material (silica particles) to an inner wall of an outer frame having sucking holes with rotating the frame, and a step of forming a silica substrate wherein the preliminarily molded article is aspirated from an outer peripheral side with controlling a humidity inside the outer frame by ventilating gases present in the outer frame with charging from inside the preliminarily molded article a gas mixture comprised of an O 2 gas and an inert gas and made below a prescribed dew-point temperature by dehumidification, and at the same time heated from inside the preliminarily molded article by a discharge-heat melting method with carbon electrodes, thereby making an outer peripheral part of the preliminarily molded article to a sintered body while an inner peripheral part to a fused glass body. With this, provided are a method for producing a silica container, having a high dimensional precision and containing extremely low amount of carbon and an OH group, with a low production cost by using main raw material powders comprised of a silica as its main component, and a silica container thereby obtained.

    摘要: The invention relates to a crucible (1) for the formation of a crystalline material by solidification by growth on seed, comprising a base (2), at least one side wall (3) orthogonal to the base (2) of the crucible (1), and means for representing the position of at least one seed intended to be positioned at the base of the crucible, said seed comprising at least first and second faces orthogonal to the base of the crucible. The representation means comprise at least two markers (4) that extend over the inner face of the at least one side wall (3) along an axis orthogonal to the base of the crucible (1). The respective positions of at least two of the markers on at least one of the side walls (3) define, in the crystalline material, a first cutting plane tangent to the first face of said seed and a second cutting plane tangent to the second face of said seed.

    摘要: Buckling of a vitreous silica crucible 12 or inward fall of a sidewall 15 is effectively suppressed. The vitreous silica crucible 12 includes the cylindrical sidewall 15 having an upward-opening rim, a mortar-shaped bottom 16 including a curve, and a round portion 17 connescting the sidewall 15 and the bottom 16. In the vitreous silica crucible 12, the per-unit area thermal resistance in the thickness direction of the sidewall 15 is higher than that of the round portion 17.

    摘要: There is provided a method for manufacturing single-crystal silicon that makes it possible to reduce occurrence of dislocation of the single-crystal silicon when the single-crystal silicon is grown using a multi-pulling method for pulling up a plurality of pieces of single-crystal silicon from a material melt in an dentical crucible. Solving Means A method for manufacturing single-crystal silicon is directed to a method for manufacturing a single-crystal silicon (1) using the multi-pulling method for pulling up a plurality of pieces of single-crystal silicon (1) from a material melt (7) in an identical crucible (8) within a chamber by a Czochralski method, the method including the step of omitting at least a part of formation of a tail part of the single-crystal silicon (1) and separating the single-crystal silicon from the material melt, wherein an amount of addition of barium formed on an inner wall of crucible (8) is controlled within a certain range.
