Melt texturing is a well-developed, if not fully understood, technique for the production of single crystals of . Although this technique can produce single crystals of up to 2 mm diameter by 25 mm in length, problems remain. For example, it is difficult to control the orientation of the crystal relative to the rod in which it grows. It is important that the crystal is oriented so that the a - b planes lie along the bar, thus maximizing the current-carrying capability of the material. This paper reports on experiments in the use of oriented seed crystals to achieve the correct single-crystal orientation relative to the bar and highlights the problems associated with the use of seed crystals.
