The mathematical treatment of dipole-dipole coupling in my previous article on magnetism applies with but little modification to the electric case. Because of fluctuation effects, the use of the usual Lorentz local field E+4πP/3 and of the Clausius-Mossotti formula cannot be justified except as a first approximation v…

The system PbO-B20 3, of interest to investigators and manufacturers of ceramic glazes and glasses, was studied by well-known methods involving quenching and petrographic examination.In addition, limits of liquid immiscibility were obtained by direct observation.Seven crystalline forms of binary compounds were found a…
Abstract Die Verbindungen (NH 4 ) 2 SbBr 6 , Rb 2 SbBr 6 und Rb 2 SbCl 6 sind kubisch, flächenzentriert, mit Metallatomen in (8e), Antimonatomen in (4b) und Halogenatomen in (24a) (Bezeichnungen nach WYCKOFF). Die Gitterkonstanten wurden zu 10,69, 10,67 und 10,17 ± 0,02 Å und der Halogenparameter zu 0,243 ± 0,003 best…
Abstract Es wurden die Schmelzdiagramme einer Reihe von Oxyden gemischt mit CeO 2 untersucht. Alle Gemische ergaben nur ein einfaches Zusammenschmelzen bis auf Cr 2 O 3 welches eine Verbindung CeCrO 3 zeigte. Das CeO 2 wurde nur beim Schmelzen in Gemischen mehr oder weniger zu Ce 2 O 3 reduziert, allein erwies es sich…

Investigation of the 3-percent chromic acid anodizing bath showed that the recommended voltage cycle was essential for formation of the best coatings. It was shown that not only could the corrosion-inhibiting properties of the coatings be improved by an increase in concentration of the electrolyte to 5 to 10 percent o…

Constants in the Born and Mayer exponential expression for the repulsion between two ions have been recalculated. Using these, the lattice energies and equilibrium distances between ions have been recomputed, for alkali halide crystals. Expressions have been derived and tested for the calculation of the compressibilit…
Single crystals of ternary alloys of nickel, cobalt and iron with forty percent nickel or more have been examined, with a pendulum magnetometer, for ferromagnetic anisotropy. All alloys in this region have face-centered cubic structures, like that of nickel. A region of low anisotropy, for nearly equal cobalt and iron…
The equili-brium of the system Cobalt-Silicon is thoroughly investigated by means of thermal, microscopic, X-ray, dilatometric and magnetic analyses, and a new equilibrium diagram is proposed. In this system there exist four compounds, i.e., Co2Si(ε), CoSi(η), CoSi2 and Co3Si(γ); the first three melt without decomposi…

A bstract Measurements have been made on “stabilized” glass fibers of five compositions in the system soda‐silica, at several temperatures in the annealing range, to obtain the viscosity, Young's modulus for instantaneous and total elasticity, and the. rate of delayed elastic distortion for each glass. Values for the…
