 Title    Beiträge zur Untersuchung anorganischer nichtstöchiometrischer Verbindungen, VII a Ein neuer einfacher Weg zur Berechnung von [(0,F)/Me]-Werten bei Blockstrukturen Contributions to the Study of Inorganic Non-Stoichiometric Compounds, VII a A New Simple Method to Calculate Values of [(0,F)/Me] for Block Structures  
 Abstract    A simple, quick and reliable method is derived to calculate values of [(0,F)/Me] for block structures. The method of calculation is exemplified using ideal and real (defect) block structures and inconsistent published data. The method represents a simple means to systematically classify block structures.

 Title    Beiträge zur Untersuchung anorganischer nichtstöchiometrischer Verbindungen, Villa Elektronenmikroskopischer Nachweis neuer, eng begrenzter Defekte bei Blockstrukturen und Berechnung ihrer O/Me-Werte Contributions to the Study of Inorganic Non-Stoichiometric Compounds, VIII a Electronmicroscopical Proof of New, Small Area Defects of Block Structures and Calculation of Their O/Me Values  
 Abstract    Compounds of the systems Fe203-Nb205 (O/Me < 2.5) and Nb205-W03 (O/Me > 2.5) were prepared by chemical transport. The block structures of the obtained phases were investigated by high resolution transmission electron microscopy. The unusual defects observed were nearly identical in both systems. A recently devel-oped method to calculate the O/Me value of block structures [ 1 ] was extended and used for these defects.

 Title    Beiträge zur Untersuchung anorganischer nichtstöchiometrischer Verbindungen, IX a Elektronenmikroskopische Untersuchungen an Kristallen aus Transportexperimenten -System Nb205-W03 (I) Contributions to the Study of Inorganic Non-Stoichiometric Compounds, IX a Electron Microscopical Investigations on Crystals Prepared by Chemical Transport in the System Nb205-W03 (I)  
 Abstract    Compounds near the composition Nb205: WO3 ~ 6:1 were prepared by chemical trans-port (at relatively low temperatures). The block structures of the obtained samples were investigated by high resolution electron microscopy. Besides unusual defects microdomains were found which still contain edgesharing blocks even at the composition 0/27Me = 2.53 to 2.55.

 Title    Beiträge zur Untersuchung anorganischer nichtstöchiometrischer Verbindungen, XXIV3 Elektronenmikroskopische Untersuchung der Hybridphasen und Nb65Oi61F3 Contributions to the Study of Inorganic Non-Stoichiometric Com pounds, XX IV 3 Electronmicroscopical Investigation of the H ybrid Phases N b590 147F and Nb650 161F3  
 Abstract    The hybrid phases N b590 147F and N b650 16iF3 were prepared at high tem perature and investi­ gated by high resolution transmission electron microscopy. Both phases have block structures. The sample of the phase N b590 147F is very well ordered, w hereas the phase N b650 161F3 shows some defects. In a sample of Nb650 161F3 m icrodom ains of a new 2:1 hybrid phase Nb960 238F4 were found. Structural differences of the systems N b20 5/N b 0 2F and N b20 5/W 0 3 are discussed.
