STRUCTURE OF TERNARY COMPOUND LaNi2Si2

摘要

＜正＞ The LaNi2Si2 alloy was prepared in a water-cooled copper crucible in an are melting furnace With a non-self-consume W electrode under an argon atmosphere. The pure components （La, 99.5%; Ni, 99.9%; Si, 99.99%） were used as raw materials. The alloy bulk was hongenized. The fine powder sample was used for X-ray diffraction after annealed in an evacuated silica tube at 400℃ in order to eliminate stresses.
