Pure lead was anodized at various constant potentials in sulfuric acid solutions. At potentials below those for formation, a layer of tetragonal is formed near the lead. is formed as an outer layer. The rate of corrosion of Pb was found to increase with increasing temperature and decreasing acid concentration and is g…
The rollers used in drafting textile fibres are disk-shaped, the lower one made of steel, the upper with a metal centre and a fairly thin elastic cover. The length over which the rollers are in contact, and the pressure distribution over this length, are factors which affect their performance as drafting agents. The p…
The kinetics of oxidation of cobalt is a complex problem since the metal forms two or more oxides and the metal itself has a phase transition from hexagonal to face‐centered cubic at a temperature between 300° and 500°C. The vacuum microbalance method is used to study the effect of time, temperature, pressure, pretrea…

Abstract Molybdänblau liegt weder eine einzige Verbindung noch eine einheitliche Reduktionsstufe zugrunde. Es hängt vom Ausgangsmaterial, dem angewandten Reduktionsmittel und der Dauer der Einwirkung des Reduktionsmittels ab, welche Verbindung gebildet wird. Die einfachen Molybdänblauarten werden in Blauoxyde und Blau…
On montre qu'il convient de distinguer au moins deux espèces de traînages magnétiques : le traînage réversible et le traînage irréversible dont on peut décrire les propriétés de la manière la plus simple, du point de vue formel, en introduisant deux champs magnétiques fictifs de traînage, dépendant du temps et superpo…

Potential‐pH Diagram of Silver Construction of the Diagram—Its Applications to the Study of the Properties of the Metal, its Compounds, and its Corrosion, Delahay, Paul, Pourbaix, Marcel, Rysselberghe, Pierre Van
On the basis of methods and conventions previously described (1) and using the available thermodynamic and electrochemical data, the potential‐ p H diagram of zinc has been constructed. Derived diagrams showing domains of corrosion, passivity, and passivation in the absence and in the presence of carbon dioxide, bicar…

On donne et l'on discute les principales propriétés des composés définis MnAs et MnBi qui permettent d'envisager, non pas un point de Curie, mais un point de transformation. Ce dernier pourrait être interprété comme un passage du ferromagnétisme à l'antiferromagnétisme.
The deterioration of polythene and other dielectrics, when exposed to internal discharges, has been examined under controlled conditions. The discharge-inception voltage and the magnitude and energy of individual discharges have been determined, and the location and number of discharges in voids of different dimension…
A comparative study of corrosion inhibition of iron by molybdate, tungstate, chromate, and nitrite was made to evaluate the relative efficiencies of the different ions and to investigate the mechanism of inhibition. It was found that both molybdate and tungstate are efficient inhibitors and comparable in this respect…
Nous donnons une étude générale des propriétés magnétiques des ferrites simples et mixtes et nous les discutons en vue d'établir les relations qui existent entre ces propriétés et la distribution des ions dans les ferrites à structure de spinelle.
The phase relationships in the zirconia‐yttria system have been established up to 2000°C. The addition of 0 to 5 mole per cent yttria lowers the temperature at which zirconia transforms from the tetragonal to the monoclinic form. From 7 to 55 mole per cent yttria is soluble in zirconia and this solid solution is cubic…
The electrodeposition of aluminum in the form of white or shiny adherent plates on various metals has been accomplished at room temperature. A satisfactory plating solution is prepared by mixing two moles of anhydrous aluminum chloride with 1 mole of ethyl pyridinium bromide, preferably in a dry, oxygen‐free atmospher…
