Experimental Study of the Ni-Se-Sn Phase Diagram Isothermal Sections at 800 K, 1000 K and 1100 K

Transformation of the crystal structure of Ni0.5TiSe2 under in situ heating

“…However, deviations from stoichiometry in NiSe x lowers the melting point to 787 °C with Ni excess and to 853 °C with Ni deficiency, as shows the solidus line of the phase diagram. 31 However, synthesizing Ni 0.5 TiSe 2 at 1000 °C results in a homogeneous product, as evidenced by the single-phase state of initial Ni 0.5 TiSe 2 at room temperature. It is possible that both NiSe melting and dissolution of nickel in the Ni x TiSe 2 structure occur simultaneously.…”
