Determination of Liquidus Temperatures of Mercury-Rich Hg--Cd--Te Alloys by Differential Thermal Analysis

Liquidus temp. have been measured for eight (Hg sub 1--x Cd sub x ) sub y Te sub 1--y compositions with 0.099 < = x < = 0.401 and 0.703 < = y < =0.900 by differential thermal analysis (DTA). The measured liquidus temp. are in good agreement with those calculated from the thermodynamic mo...

Zusammenfassung:Liquidus temp. have been measured for eight (Hg sub 1--x Cd sub x ) sub y Te sub 1--y compositions with 0.099 < = x < = 0.401 and 0.703 < = y < =0.900 by differential thermal analysis (DTA). The measured liquidus temp. are in good agreement with those calculated from the thermodynamic model of Tung, et al . The change in liquid composition caused by Hg vaporization into the free volume of the DTA ampule introduces an error in the liquidus temp. of < 1.5 deg C.--AA
