Abstract

1,103,906. Bismuth telluride. SIEMENSSCHUCKERTWERKE A.G. 21 Sept., 1965 [22 Sept., 1964], No. 40270/65. Heading B1S. A crystal 4 of bismuth telluride is pulled from a melt 2 in a heated crucible 1 through a die having two successive portions 6 and 7, of boron nitride and boron carbide respectively, portion 6 being of lower thermal conductivity than portion 7. The formation of a convex solidification face may be enhanced by means of a surrounding induction coil 9 or by means of a conical partition face between portions 6 and 7 (Fig. 2). A heat exchanger 5 provides heat dissipating means.
