    Springer

    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Regularly shaped single-crystalline, hexagonal, and hollow Sr-Er- and Sr-Dy-sialon microtubes were yielded by high-temperature reaction using a radio-frequency furnace at 1600 °C and 1670 °C, respectively. Starting materials were silicon diimide (Si(NH)2), AlN, Sr and Er or Dy, respectively. The carbonates Er2(CO3)3 and SrCO3, respectively, have been used as oxygen providing reactants. The sialon microtubes had an average diameter between 3 and 25 μm and an average length between 30 and 150 μm.

    Nitrido-Sodalithe. II. Synthese, Struktur und Eigenschaften von M(6+(y/2)-x)H2x[P12N24]Zy mit M = Fe, Co, Ni, Mn; Z = Cl, Br, I; 0 ≤ x ≤ 4; y ≤ 2 (1995)

    Description / Table of Contents: Nitrido-Sodalites. II. Synthesis, Crystal Structure, and Properties of M(6+(y/2)-x)H2x[P12N24]Zy with M = Fe, Co, Ni, Mn; Z = Cl, Br, I; 0 ≤ x ≤ 4; y ≤ 2The nitrido sodalites M(6+(y/2)-x)H2x[P12N24]Zy with M = Fe, Co, Ni, Mn; Z = Cl, Br, I; 0 ≤ x ≤ 4; y ≤ 2 are obtained by the reaction of HPN2 or [PN(NH2)2]3 with the metal halogenide MZ2 (T = 700°C). The compounds are isotypic to Zn(7-x)H2x[P12N24]Cl2. An increase of the ionic radii of the cations or anions results in an expansion of the lattice which is caused by an increase of the P—N—P angle. The influence of the cation is more dominant than that of the anion. By reacting [PN(NH2)2]3 with metal halogenide (MZ2) hydrogen free, X-ray amorphous products are obtained. The formation of the chloride-containing P—N-sodalite in this reaction begins at temperatures below 450°C.
    Notes: Die Nitrido-Sodalithe M(6+(y/2)-x)H2x[P12N24]Zy mit M = Fe, Co, Ni, Mn; Z = Cl, Br, I; 0 ≤ x ≤ 4; y ≤ 2 wurden durch Umsetzung von HPN2 bzw. von [PN(NH2)2]3 mit dem jeweiligen Metallhalogenid MZ2 hergestellt (T = 700°C). Sie sind mit Zn(7-x)H2x[P12N24]Cl2 isotyp. Mit steigendem Ionenradius von Kationen oder Anionen findet man eine Aufweitung des Volumens. Dies ist mit einer Vergrößerung des P—N—P-Winkels verbunden. Der Einfluß der Kationen ist dabei stärker als jener der Anionen. Durch Reaktion von [PN(NH2)2]3 mit dem jeweiligen Metallhalogenid MZ2 werden wasserstofffreie P—N-Sodalithe als röntgenamorphe Pulver erhalten. Bei diesen Reaktionen setzt die Bildung der chlorhaltigen P—N-Sodalithe schon unterhalb von 450°C ein.

    Description / Table of Contents: Nitrido-silicates. III [1] High-Temperature Synthesis, Crystal Structure, and Magnetic Properties of Ce3[Si6N11]Pure Ce3[Si6N11] was obtained as transparent yellow crystals by reaction of metallic cerium with silicon diimide (Ce:Si = 1:2) under nitrogen atmosphere in a specially developed high-frequency furnace at 1660°C. Ce3[Si6N11] (P4bm, a = 1013.7(3), c = 483.9(5) pm, Z = 2, R = 0.034, wR = 0.024) contains Ce3+ ions as well as a three-dimensional covalent anionic network structure of corner-sharing SiN4 tetrahedra. Measurements of the magnetic susceptibility gave no indications for magnetic ordering phenomena in the temperature range between 2 and 300 K. Above 100 K pure Curie-Weiss behaviour (μeff = 2,10 μB, determined at room temperature) was observed.
    Notes: Transparent gelbe Kristalle von Ce3[Si6N11] wurden phasenrein durch Umsetzung von metallischem Cer mit Siliciumdiimid (Ce:Si = 1:2) unter Stickstoffatmosphäre in einem speziellen Hochfrequenzofen bei 1660°C synthetisiert. Ce3[Si6N11] (P4bm, a = 1013,7(3), c = 483,9(5) pm, Z = 2, R = 0,034, wR = 0,024) besteht im Festkörper aus Ce3+-Ionen sowie einer kovalenten, dreidimensional vernetzten Anionenteilstruktur eckenverknüpfter SiN4-Tetraeder. Messungen der magnetischen Suszeptibilität ergaben keine Hinweise auf magnetische Ordnungsphänomene im Temperaturbereich von 2 bis 300 K. Oberhalb 100 K wurde reines Curie-Weiss-Verhalten (μeff = 2,10 μB, ermittelt bei Raumtemperatur) beobachtet.

    Description / Table of Contents: Nitrido-Sodalites. III. Synthesis, Crystal Structure, and Properties of Zn8[P12N24]X2 with X = O, S, Se, TeThe P—N-sodalites Zn8[P12N24]X2 with X = O, S, Se, Te are obtained by the reaction of HPN2 with the corresponding zinc chalcogenide ZnX at 750°C. They crystallize in a filled up variant of Zn7[P12N24]Cl2 and are isotypic to Zn8[B12O24]O2 (I43m, a = 823 to 830 pm, Z = 1). The P—N-sodalites contain in the center of their β-cages XZn46+ units which can be described as sections of II/VI-semiconductors. The UV/Vis-spectra of the compounds show in comparison with binary bulk zinc chalcogenides a blue shift of the absorption edge according to the size quantization effect.
    Notes: Die P—N-Sodalithe Zn8[P12N24]X2 mit X = O, S, Se, Te wurden durch Umsetzung von HPN2 mit dem jeweiligen Zinkchalkogenid ZnX bei 750°C dargestellt. Sie kristallisieren in einer aufgefüllten Variante von Zn7[P12N24]Cl2 und somit isotyp zu Zn8[B12O24]O2 (I43m, a = 823 bis 830 pm, Z = 1) Die P—N-Sodalithe enthalten im Zentrum ihrer β-Käfige XZn46+-Einheiten, die als kleinstmögliche Ausschnitte aus den Strukturen von II/VI-Halbleitern angesehen werden können. Die UV/Vis-Spektren der Verbindungen zeigen im Vergleich mit makrokristallinen binären Zinkchalkogeniden gemäß dem Größenquantisierungseffekt eine Blauverschiebung der Absorptionskante.
