Description / Table of Contents:
The ternary compounds with the structure of the NaZn13 type were found in the course of the X-ray investigation of the systems lanthanum-nickel-silicon (∼ LaNi10.5Si2.5, a = 11.27-11.35 Å) and lanthanum-iron-silicon (∼ LeFe11.5Si1.5, a = 10.51-10.52 Å); one can regard these compounds as the members of two isoelectronic series, one beginning with LaZn13 and other with LaCo13. The ternary phases of the NaZn13 type in the systems lanthanum-cobalt-silicon and lanthanum-cobalt-aluminium are solid solutions based on LaCo13. Compounds of the NaZn13 type are formed also in the systems cerium-cobaltsilicon (Ce(Co, Si)13, a = 11.36 Å), praseodymium-cobalt-silicon (∼ PrCo10.5Si2.5, a = 11.28 Å) and neodymium-cobalt-silicon (∼ NdCo10.5Si2.5, a = 11.24 Å).
Notes:
Die ternären Verbindungen vom NaZn13-Typ wurden bei der röntgenographischen Strukturuntersuchung der Systeme Lanthan-Nickel-Silicium (∼ LaNi10,5Si2,5, a = 11,27 bis 11,35 Å) und Lanthan-Eisen-Silicium (∼ LaFe11,5Si1,5, a = 10,51-10,52 Å) gefunden; diese Verbindungen kann man als Glieder der isoelektronischen Reihen, die mit LaZn13 bzw. LaCo13 beginnen, ansehen. Die ternären Phasen von demselben Typ in den Systemen Lanthan-Kobalt-Silicium und Lanthan-Kobalt-Aluminium sind LaCo13-Mischkristalle. Die Verbindungen vom NaZn13-Typ bilden sich auch in den Systemen Cer-Kobalt-Silicium (Ce(Co, Si)13, a = 11,36 Å), Praseodym-Kobalt-Silicium (∼ PrCo10,5Si2,5, a = 11,28 Å) und Neodym-Kobalt-Silicium (∼ NdCo10,5Si2,5, a = 11,24 Å).
