 Title    Crystallisation Processes in Metal Rich Rubidium Oxides  
 Abstract    On the basis of X-ray investigations a structural model for the orientational disorder of Rbg02 clusters in the rubidium suboxide RbeO is derived, which is in accordance with details of the thermal analysis of the ordering process. In the second part the thermal and structural investigations of a metastable phase of the probable composition Rbe,330 are described. The phase is formed by warming quenched samples Rb;rO (9 >x > 7) to co. 140 K and decomposes at ca. 183 K. Its cubic structure bears relationships to the structure of rubidium as well as to YBe6 (replacing B12 icosahedra in the latter compound by Rb atoms). A special DTA instrument used for the investigation of Rbe.330 is described.
