    摘要: A method of manufacturing a composite crucible includes: supplying mullite material powder to an upper region of a mold, and supplying second silica powder to a lower region provided below the upper region while rotating the mold; supplying third silica powder on an inner surface side of a layer made of the mullite material powder and the second silica powder; heating and fusing the mullite material powder, the second silica powder, and the third silica powder to form an opaque vitreous silica layer provided on the outer surface of the crucible, a transparent vitreous silica layer provided on an inner surface side of the crucible, and a mullite reinforcement layer provided on the outer surface side of an upper end portion of the crucible.
