摘要: A mold for making a fused silica crucible includes a cylindrical can having an interior bore. A graphite insert is received in the bore and has an upper surface adapted to form the lower surface of the crucible while the interior bore of the can forms the side wall of the crucible. Silica grain is deposited in the mold while it rotates. Bores formed in the can above the insert and in the insert draw air through the silica during fusion.
