摘要：
The constitution of the Pd-Te system has been completed in the palladiumrich range up to 28 at.% Te and temperatures above 600°C. The shapes of solidus and liquidus have been reliably determined for the first time. The solid solution between palladium and tellurium has a maximum tellurium content of 16.3 at.% at approximately 770°C. The system shows a eutectic with 23.0 at.% Te at 773°C. Three phases were observed in the subsolidus region, i.e. Fd17Te4 (19 at.% Te), Pd20Te7 (26 at.% Te) and dimorphic Bd3Te (25 at.% Te) which exists only above 721°C. Our findings are compatible with those already established for the system towards higher tellurium concentrations. © 1990.
