Qısa məlumat

By DTA, X-ray diffraction, EMF methods and microhardness measurements, the phase equilibria on the concentration sections Tl5Te3-Tl4PbTe3-Tl 9BiTe6 (I), Tl2Te-Tl4PbTe3-Tl9BiTe6 (II), Tl5Te3-Tl9NdTe6-Tl 9BiTe6 (III) and Tl2Te-Tl9NdTe6-Tl9BiTe6 (IV) of the multinary systems Tl-Pb(Nd)-Bi-Te were investigated. A number of isopleth sections, projections of liquidus and solidus surfaces of the systems (I)-(IV) were constructed. The concentration dependences of crystal lattice parameters, microhardness and of partial thermodynamic functions of thallium (Δ over(G, ̄), Δ over(H, ̄), Δ over(S, ̄)) in alloys were determined. The investigated systems are characterized by formation of continuous (I, III) or wide (II, IV) areas of solid solutions based on Tl5Te3 compound. © 2009 Elsevier B.V. All rights reserved.
