During an investigation
of the interaction of
the components in the Li–Sn–Si
system, the existence of seven binary compounds was confirmed in the Li–Sn system by means of X-ray powder diffraction. A
continuous series of solid solutions was found between the Li17Sn4
and Li17Si4 binary intermetallides
with Li17Pb4-type structure. The cell parameters within
the solid solutions change approximately according to Vegard’s
law (Li17Sn4-õSiõ (õ = 0‑4), à = 1.9714(1)-1.8718(1) nm). The
variation of the lattice parameters within the limited solid solutions based on
LiSn (up to 10 at.%) and Li7Sn3
(up to 5 at.%) binary compounds was also determined.
Atomic layers at z = 0 and 1/2 in the structure of the LiSiõSn1-õ
(õ = 0-0.2) solid solution.
