Ultrasonic velocity measurements in liquid Cd-x-Te1-x alloys

Ultrasonic velocities, v(s), in liquid CdxTe1-x alloys (x=0.0, 0.1, 0.2, 0. 25, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0) have been measured in the range from liquidus temperature to 1200 degrees C under the saturated vapour pre ssure of Cd and Te. The isotherms of v(s) show have an inflection at 50 at. % of Te corresponding to the CdTe solid compound. Results indicate the bond ing in the Cd-Te system changes at 50 at.% Te. Discussion is also given on supercooling temperatures as compared with an optimized liquidus line propo sed previously. (C) 1999 Elsevier Science B.V. All rights reserved.
