The reaction was studied at 19 Torr pressure under static and flow conditions. Rates of reaction up to were measured at 1650°C and 19 Torr. The rates of reaction were nearly independent of flow and pressure. The kinetic data could be fitted to an Arrhenius‐type equation , where . Mass spectrometer studies of the react…

Rates of film growth in oxygenated dilute sulfuric acid have been measured on zirconium and Zircaloy‐2 at temperatures from 200° to 300°C using electrochemical methods. The resulting rate‐time plots were analyzed according to logarithmic and cubic kinetics. The kinetic constants obtained from these results, and those…
Plasticizatlon, in general, refers to a change in the thermal and mechanical properties of a given polymer which involves: (a) lowering of rigidity at room temperature; (b) lowering of temperature, at which substantial deformations can be effected with not too large forces; (c) increase of the elongation to break at r…
The statistics of photoemission as computed based on a Poisson distribution of incident photons, and a binomial distribution for the photocurrent, exactly obeys a Poisson distribution so that the fluctuation in the photocurrent is just that associated with the standard deviation of a Poisson distribution. This is comp…

The spiralling of the current in steel-cored aluminium conductors sets up an axial magnetic flux, and at power frequency this results in power loss from hysteresis in the steel core and from eddy currents. This loss increases with current and raises the a.c. resistance of the conductor; the internal inductance also in…

Abstract Experimental results obtained over a wide range of variables from three different foam fractionation columns support the theory developed in Part I.

Abstract The decomposition of iron pentacarbonyl at pressures between one and 400 Torr was studied from 120° to 300°C. Up to about 200°C. the rate was primarily limited by surface kinetics of adsorbed carbonyl. Gas phase diffusional resistances were controlling at higher temperatures. In the kinetically controlled reg…
Abstract The distribution of cations in MgMn 2 O 4 is studied between 25 and 1000 °C by X‐ray diffraction. The values of the c/a ratio agree with the observed repartition of the cations. From the inversion of the distribution at high temperature the activation energy of the ionic migration is inferred: θ = 8100‐−18400…
The formation of several intermediate oxides of niobium, produced in the course of transformation γ-Nb 2 O 5 → α-Nb 2 O 5 and the reaction Nb 2 O 5 +Nb→ NbO 2 , has been studied by X-ray diffraction. The structure transformation γ→α is accomplished by a passage through two intermediate stages, γ' and β. The γ' form is…
The relationship between dissolution kinetics and resistance to pitting corrosion has been investigated using electrochemical measurements. It is shown that the ratio of dissolution rates in the presence and absence of chloride ion is inversely related to pitting resistance. The above concepts have been used to predic…
Solid solution between and of stoichiometric composition has been studied. It is found that for samples annealed at 600°C for periods of up to four weeks and then air quenched, single phase condition can be obtained at all alloy compositions, and the lattice shows a continuous transition from cubic to rhombohedral for…
The first- and second-order Raman spectra of calcium fluoride have been measured. With the crystal at room temperature the structure observed is in good agreement with earlier measurements of infra-red absorption and vibronic satellites. Some additional structure observed in the second-order Raman spectrum is ascribed…
Experiments have been carried out at 386°C to determine the concentration of anion vacancies at the metal‐oxide interface and the diffusion coefficients for anion vacancies in zirconium dioxide films on zirconium by the "interruption kinetic technique." The conditions for which this technique is valid are discussed. T…
