The Zr-Te phase diagram has been investigated by X-ray powder diffract
ion and Differential Thermal Analysis (DTA) measurements. Seven compou
nds were found in the Zr-Te system, of which only the compound Zr1+xTe
2 has a homogeneity range. Enthalpy effects of twenty Zr-Te samples wi
th different compositions have been measured by DTA. The melting tempe
ratures of the compounds Zr3Te, Zr5Te4, ZrTe3, and ZrTe5 have been det
ermined, and a tentative phase diagram is suggested. (C) 1997 Elsevier
