Condition diagram of the Sb2Te3–La2Te3 cut has been researched  by the differential, thermal, X-ray, microstructural analysis methods as well as microhardness and density measurement. It was found that cut is the quasibinary section of La– Sb–Te triple system. In the system there forms triple chemical combination consists on LaBiTe3 crystallized in hexagonal lattice with the following parameters: a=4.24 c=30.64 Å  (c/a=7.21). Solubility on Sb2Te3 side at  room temperature is 6 mol.%. Electrophysical properties of LaSbTecompound  have  been investigated too.
