             abstract = "Transition metal dichalcogenides have been receiving considerable 
                         attention in the literature due to their great variety of physical 
                         properties. Recently, some compounds of this family have been 
                         pointed out as new examples of Dirac and Weyl semimetals. However, 
                         the lack of thermodynamic data or experimental studies on these 
                         binary systems makes the synthesis of high-quality samples purely 
                         empirical. This report investigates the binary Nb-Te phase 
                         diagram. Results of x-ray diffraction, Rietveld refinement, 
                         scanning electron microscopy, and differential thermal analysis 
                         strongly suggest that Nb5Te4 and Nb3Te4 are stable only at high 
                         temperatures. These phases decompose according to the following 
                         eutectoid reactions: Nb3Te4(s) ? Nbss ? NbTe2(s) at 735 C and 
                         Nb5Te4(s) ? Nbss ? Nb3Te4(s) at 839 C. Furthermore, the results 
                         presented in this study show that NbTe2 and NbTe4 are the only 
                         stable compounds in the Te-rich portion of the phase diagram ([60 
                         at.% of Te) at temperatures below 735 C.",
