 Title    IR Spectrum of Scandium Orthovanadate1  
 Abstract    M a r t a E . E s c o b a r und E n r i q u e J. B a r a n The infrared spectrum of ScYO4 is reported and discussed in comparison with those of YVO4 and of the lighter lanthanide ortho-vanadates. In order to facilitate the vibra­ tional assignment the spectra of a series of solid solutions of the type Sc(V0 4)i_w(P0 4)n are also measured and analyzed.

 Title    Gläser und Verbindungen im System P4S4-A s 4S4-A s 4Se4-P 4Se4 Glass and Com pounds in the System P4S4-A s 4S4-A s 4Se4-P 4Se4  
 Abstract    Glas forming regions and glass temperatures o f the system P4S4-A s 4S4-A s 4Se4-P 4Se4 have been determined by thermoanalytical and X-ray methods. In the whole system crystalline sam­ ples have been obtained by annealing. From the pure phases A s4S4 and P4Se4 broad regions o f solid solutions extend into the system. In the P4S4 corner the form ation o f A 4B3 (A = P, As; B = S, Se) molecules is observed. As with A 4B3 m olecules, a stepwise substitution o f P by As atoms, and o f S by Se atom s is possible. All molecules o f the series P4_"As"S4 and A s4S4_"Sen (n = 0, 1, 2, 3, 4) were detected by 31P N M R and/or mass spectroscopy.

 Title    Chemischer Transport fester Lösungen am Beispiel von Mischspineilen Chem ical Transport o f Solid Solutions: M ixed Spineis  
 Abstract    Chemical vapor transport is a suitable pathway to controllable syntheses of mixed spinel systems. Solid solutions of spinels on the basis of 3d transition metal oxides and gallium oxide can be prepared using various transport agents (TeCl4, Cl2, HC1). Transport processes observed are consistent with theoretical predictions.

 Title    Die quaternären Systeme ZnAl2S4-ZnGa2S4, ZnAl2S4-CdAl2S4 und ZnAl2S4-ZnAl2Se4. Röntgenographische und schwingungsspektroskopisehe Untersuchungen Investigation of the Quaternary Systems ZnAl2S4-ZnGa2S4, ZnAl2S4-CdAl2S4, and ZnAl2Se4-ZnAl2Se4 by X-Ray Diffraction and Vibrational Spectroscopy  
 Abstract    The quasi-binary systems Zni_a:Cda;Al2S4, ZnAl^i-zjGao.^, and ZnAl2S4(i_a;)Se4:r have been investigated by X-ray diffraction and vibrational spectroscopy. In the spinel Z11AI2S4 up to 20% of Zn can be replaced by Cd. In the two other systems, ZnAl2S4 has no detectable homogeneity range. The thiogallate phases have much broader ranges of homogeneity. The compositions of the compounds at the phase boundary of the thiogallate phase are Zno.4Cdo.6Al2S4, ZnGao.4Alx.6S4, and ZnAl2S2.8Sei.2. At approximately 950 °C ZnAl2Se4 undergoes a reversible phase transition to a wurtzite-type structure. This phase transition is also observed for the solid solutions ZnAl2S4(i_a;)Se4a; with 1.0 > x > 0.3. The FIR spectra are discussed.
