  , , , and their phase‐mixtures by varying the germanium ion concentration in the molten bath. Germanium was found to be more noble than niobium in the molten fluoride bath, thus facilitating the deposition of germanium rich alloys. The superconducting compound, , however, could not be obtained as a single‐phase deposit. It was obtained only as a minor constituent in certain phase‐mixtures when operating

  铌锗合金是通过在共晶溶剂中含有 5 mol% 和不同浓度 的熔融氟化物溶液通过电沉积获得的。熔浴温度通常为约750℃。阴极（或基板）由钼和钨箔制成，锗片用作溶解阳极。通过改变熔池中锗离子的浓度，金属间化合物、、、和它们的相混合物获得了稳定生长的沉积物。发现在熔融氟化物浴中，锗比铌更贵重，因此有利于富锗合金的沉积。然而，超导化合物不能作为单相沉积物获得。在极端条件下操作时，它仅作为某些相混合物中的次要成分获得。

  Nb‐Ge films, which have been prepared by chemical vapor deposition, have been studied for superconducting transition temperatures, crystal structures, and growth morphology. In the films a relationship was obtained among positions at which the highest Tc films are deposited, the degree of orientation for A15 crystallites is lowered, and the microstructures for film surface change has been found. This

  已经通过化学气相沉积制备的 Nb-Ge 薄膜已经研究了超导转变温度、晶体结构和生长形态。在薄膜中，获得了最高 Tc 薄膜沉积位置之间的关系，A15 微晶的取向度降低，并发现了薄膜表面变化的微观结构。这可以通过 Ge 的沉积速率高于 Nb 的沉积速率来解释。

  AbstractThe binary germanides M12Ge17 and M4Ge9 (M  Na, K, Rb, Cs) and the stannides M12Sn17 and M4Sn9 (M  K, Rb, Cs) were identified by a combination of direct synthesis, thermogravimetric analysis, vibrational spectroscopy, X‐ray powder data and single crystal structure analysis. The M12E17 phases contain the cluster anions [E9]4− and [E4]4− in the ratio 1:2, forming a hierarchical structure with the cluster anions at the atomic positions of the hexagonal Laves phase MgZn2. Like the M4E4 phases, the M4Ge9 compounds are hierarchical derivatives of the cubic Cr3Si structure but with [Ge9]4− anions. The thermogravimetric analyses give strong evidence for the existence of at least one more phase with [E9]4− and [E4]4− clusters and of the clathrate phases M6E136 in addition to the well‐known M8E44□2 chlathrates.
