This paper describes measurements of the tellurium vapour pressures over sa
mples consisting of Zr1+xTe2, as a function of temperature T and sample com
position using the Knudsen effusion mass-loss method. The integral Gibbs en
ergy of the Zr-Te system as a function of composition has been calculated f
rom the tellurium vapour pressures. (C) 1999 Academic Press.
