PHASE EQUILIBRIA IN THE TERNARY SYSTEM Dy–Lі–Sі AT 400 °С
Journal Title: Праці Наукового товариства ім. Шевченка - Year 2017, Vol 48, Issue
Abstract
The isothermal cross-section of the phase diagram of the system Dy–Li–Si based on X-ray phase and local X-ray spectral analyses was constructed at the temperature 400 °С in the range 30–100 аt. % Si. Six new ternary compounds have been synthesized for the first time: DyLiSi2 (SТ NdRuSi2, Pearson symbol mP8, space group P21/m, a = 0.4010(1), b = 0.3869(1), c = 0.8119(2) nm, β = 102.32°, RB = 0.066), DyLiSi (SТ ZrNiAl, Pearson symbol hP9, space group P-62m, a = 0.7011(2), c = 0.4193(1) nm, RB = 0.059), DyLi0.35Si1.65 (SТ α-ThSi2, Pearson symbol tI12, space group I41/amd, a = 0.4039(2), c = 1.3912(5) nm, RB = 0.073), DyLi5Si4 (unknown structure), Dy4LiSi4 (unknown structure) and DyLi3Si (unknown structure). All these compounds have been refined using powder X-ray diffraction data (diffractometers STOE STADI P and URD-6 (Cu Kα-radiation)). The existence of the binary phases DySi2-x, DySi2, DySi, Dy5Si4, Dy5Si3, Li22Si5, Li13Si4, Li14Si6, Li12Si7, Li2Si was confirmed. Solubility of the third component in the binary compounds was not observed.
