Low temperature region of the ternary Pb-In-Se system

The triangulation of the Pb-In-Se system has been performed using XRD and E DX measurements. in addition to six binary phases, two ternary phases were observed, the ternary diagram is thus divided at room temperature into 11 s econdary triangles. Two forms have been obtained at room temperature for In 2Se3, but the corresponding secondary triangle, because of its narrowness, could not be observed. No ternary solubility in the binary intermediate and terminal phases has been observed. (C) 2000 Elsevier Science S.A. All righ ts reserved.
