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 = 7.7640 Å; b = 6.4144 Å; and c = 3.6010 Å, α = β = γ = 90°. The system also contains PbSb2Te4 and InSb based boundary solid solutions extended from 0 to 10 and from 95 to 100 mol% InSb, respectively, at room temperature.
►The state diagram in the PbSb2Te4–InSb system is built. ► The system contains the PbSb2Te4·(2 ± δ)InSb compound of variable composition, which crystallizes in orthorhombic symmetry. ► The system contains PbSb2Te4 and InSb based boundary solid solutions.
