  • Publication number: 20140352605
    Abstract: Making a barium-doped silica crucible includes forming a crucible by introducing into a rotating crucible mold bulk silica grains to form a bulky wall. After heating the interior of the mold to fuse the bulk silica grains, an inner silica grain, doped with barium, is introduced into the crucible. Residual heat or additional heat at least partially melts the inner silica grain, allowing the barium-doped silica layer to fuse to the wall of the crucible to form a glossy inner layer. Next, at least a part of the barium-doped silica layer is roughened. Also described are the crucible made thereby as well as silicon ingots made using the crucibles as described herein.
