Patent number: 8685161Abstract: Various single crystals are disclosed including sapphire. The single crystals have desirable geometric properties, including a width not less than about 15 cm and the thickness is not less than about 0.5 cm. The single crystal may also have other features, such as a maximum thickness variation, and as-formed crystals may have a generally symmetrical neck portion, particularly related to the transition from the neck to the main body of the crystal. Methods and for forming such crystals and an apparatus for carrying out the methods are disclosed as well.Type: GrantFiled: February 14, 2012Date of Patent: April 1, 2014Assignee: Saint-Gobain Ceramics & Plastics, Inc.Inventors: John W. Locher, Steven A. Zanella, Ralph L. MacLean, Jr., Herbert Ellsworth Bates

Patent number: 5398640Abstract: 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.Type: GrantFiled: March 1, 1993Date of Patent: March 21, 1995Assignee: Saphikon, Inc.Inventors: John W.
