Abstract

The phase diagram of the W-Te system as proposed by [1] and redrawn by [2] is shown in Fig. 119. The orthorhombic (space group Pmmn) ditelluride has been identified as the only intermediate phase [3 to 5], see the reviews [6 to 8]. The formation of WTe4 as a thin coating on tungsten in Te melts at high temperatures (>700°C) is assumed in [9]. The solubility of W in Te is low (< 0.3 at%), as microscopic studies show [3].
