摘要： During fabrication of a vitreous silica crucible, contamination of the vitreous silica crucible due to wear particles and debris of components of an apparatus for manufacturing a vitreous silica crucible is reduced by preventing damage and wear of the components of the apparatus due to silica fume. The apparatus for manufacturing a vitreous silica crucible is divided into a lower section for accommodating a mold and a mold driving system and an upper section for accommodating an arc electrode driving system, wherein a sectioning member including one or more communication paths for allowing penetration of arc electrodes, thereby the air flow is controlled so as to reduce exchange between gas in the upper section and gas in the lower section.

摘要： The method of producing a vitreous silica crucible, comprises deposition step of depositing silica powder on an inner wall surface of a cylindrical rotation mold having a bottom while rotating the mold; and a fusion step to obtain a vitreous silica crucible by heating and fusing the silica powder deposited on the inner wall surface of the mold and thereby vitrifying the silica powder. In the deposition step, a density of the deposited silica powder layer on the inner wall surface of the mold is controlled within a predetermined range by controlling the electrostatic charging voltage of the silica powder to be in a range of 1.0 kV or less in absolute value, and supplying the thus controlled silica powder to the inner wall surface of the mold. Thus, a wall thickness of the vitreous silica crucible is controlled.
