Phase equilibria and structural investigations of the general NiAs-type in the ternary system Ni–Sn–Te

Experimental investigation of the ternary system Ni–Pd–Sn with special focus on the B8-type phase

“…Related situations were observed in the ternary systems Ni-Sn-Te and Ni-Pt-Sn. In Ni-Sn-Te, a maximum between the continuous B8-phase field and the binary intermediate phase SnTe is formed in the three-phase field {L+B8+SnTe}at around 790 °C[1]. In Ni-Pt-Sn, nearly the same situation as in the currently investigated system was observed.…”

“…A second factor that may influence the behaviour of the lattice parameters is the occupation of the trigonal-bipyramidal position (atomic site 2d) with transition metals. As recently described for the systems Ni-Sn-Te[1] and Ni-Pt-Sn[2], filling of this position with additional transition-metal atoms leads to an increase of the lattice parameter a.Hence, in the system Ni-Pd-Sn the decrease of transition-metal content along the section Ni 0 Pd 64 Sn 36 -Ni 58 Pd 0 Sn 42 leads to a decrease of the lattice parameter a.…”

Thermodynamic modelling of the general NiAs-type structure: A study of first principle energies of formation for binary Ni-containing B8 compounds

“…According to a new investigation of the ternary system Ni-Sn-Te [45], where a continuous solid solution, including regions of CdI 2 -, NiAs-and Ni 2 In-type, was observed, a modified sublattice model according to the compound energy formalism (CEF) was suggested for future Calphad modelling. Three endmembers of this new sublattice model represent the boundary structures of the general NiAs-type structure (CdI 2 , NiAs, Ni 2 In).…”

“…For example, it was shown for the ternary system Ni-Sn-Te that a continuous solid solution from 34 to 64 at% Ni is formed in the ternary, covering regions of CdI 2 -, NiAsand Ni 2 In-type [45].…”

Phase Equilibria of the Sn–Ni–V System: The 980°C Isothermal Section and the Sn-Rich Corner at 600°C and 300°C

“…They originate from ordering of Ni atoms and vacancies on trigonal-bipyramidal sites, forming a commensurate superstructure LT, whereas LT¢ and LT¢¢ are incommensurate. 13 The high-temperature modifications of Ni 3 Sn and Ni 3 Sn 2 melt congruently at 1189°C and 1280°C, respectively. Ni 3 Sn 2 -HT contains Ni-rich compositions in the range between Ni 2 In and NiAs (56-63 at.% Ni).…”
