Phase Diagram for the Pseudobinary System of Sb-SnTe and Some Electrical Properties of the Ternary Alloys

The Sb-SnTe pseudobinary phase diagram is a simple eutectic system with the eutectic point at 576°C and Sb85.8(SnTe)14.2. The limits of solubility are Sb10 (SnTe)90 and Sb97 (SnTe)3 at 525°C The latter result does not agree with Krebs (3) who obtained a solubility limit of Sb87.0(SnTe)13.0 for samples annealed 24 hr near 470°C The increase in crystal volume of Sb with the addition of 3 mole % SnTe is 0.06%. The addition of 10 mole % Sb to SnTe causes no significant change in lattice parameter from SnTe. The electrical properties of Sb1.8(SnTe)98.2 are similar to those of SnTe. © 1966, The Electrochemical Society, Inc. All rights reserved.
