    Abstract: A quartz glass crucible for use in pulling up a silicon single crystal, wherein it has, at least in the curved portion thereof, a three-layer structure comprising a transparent inner layer being composed of a synthetic quartz glass and having a low Al concentration, a transparent or nontransparent intermediate layer being composed of a natural quartz glass or a mixture of natural and synthetic quartz glasses and having a high Al concentration, and a nontransparent outer layer being composed of a natural quartz glass and having an Al concentration higher than that of the intermediate layer. The quartz glass crucible is reduced in the deformation of the transparent inner layer, and allows the suppression of the change in the amount of dissolution of the quartz glass crucible associated with the pull-up of a single crystal and the achievement of the uniform oxygen concentration in the longitudinal direction of a single crystal.

    Abstract: PURPOSE: Provided is a quartz glass crucible having high purity at the part of its inner circumference, suitable to be used in a method for pulling monocrystalline silicon for semiconductors from molten silicon. CONSTITUTION: The quartz glass crucible is manufactured by heating powder of quartz raw material present in the inside of a hollow rotational mold(10) with electric arc, wherein an electric voltage is applied between the mold(10) and an arc electrode(13) to cause metal impurities contained in the molten quartz glass disposed at the inner circumference of the crucible to be moved toward the outer circumference so that the purity of the molten quartz glass is increased. The arc-melting of the quartz material is performed until the thickness of the resultant glass layer becomes a thickness of 5 mm or more and that of the non-molten quartz glass layer becomes 2 mm or less. During the arc-melting, an earth arc electrode is maintained at a potential of +/- 500V. A voltage of -1,000 to -20,000 V is applied to the mold electrically insulated with the earth.
