 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.
