  • Apparatus for growing hollow crystalline bodies from the melt
    Patent number: 5398640
    Abstract: A single crystal dome is formed from a surface of revolution and grown from a liquid material on a linear die surface wettable by the molten material. A seed crystal is supported in a position spaced from an axis of revolution which lies in the plane of the wettable surface, and the seed crystal is rotated around the axis of revolution to generate a curved surface having a predetermined radius of curvature. The seed crystal is supported in a predetermined orientation of one of its axes with respect to the wetted surface of commencement of growth.
