The binary system Bi-Sb, which presents a complete solid solution is accepted from [Mas2]. The Bi-Te
system is still controversial. The widely accepted stable phases are BiTe and Bi2Te3. No assessment of this
diagram has been presented since the review of [Mas2] who proposes a compromise between many
contradictory experimental results and reports at least 9 other phases, probably metastable sequences of
ordered stacking. The Sb-Te system is accepted form the extensive review of
