Summary: | A phase diagram of the PbSb₂Te₄–InSb system, which is polythermal cross section of the three-component PbTe–Sb₂Te₃–InSb system, was built using DTA, XRD, microhardness and density measurements. The system contains the PbSb₂Te₄·(2±δ)InSb compound of variable composition, incongruently melting at 530±5°C, and with asymmetric area of homogeneity shifted to the side rich in InSb (+δ=0–2). The PbSb₂Te₄·2InSb compound crystallizes in orthorhombic symmetry with unit cell parameters: a=7.7640Å; b=6.4144Å; and c=3.6010Å, α=β=γ=90°. The system also contains PbSb₂Te₄ and InSb based boundary solid solutions extended from 0 to 10 and from 95 to 100mol% InSb, respectively, at room temperature. |
