The effect of oxide impurity on the conductivity of potassium chloride

Creator:: Kouts, Daberath
Abstract:: Direct current conductivity measurements on KC1:O[superscript]= crystals were used to determine an enthalpy of 0.42 ev for the dissociation for anion-vacancy-oxide ion complex. The entropy of dissociation was found to be approximately -4x 10⁻⁴ev deg⁻¹. The intrinsic "activation" energy was found to be 1.91 ev as compared to 1.95 ev,...

The electrical properties of vanadium pentoxide

Creator:: McCulloch, John Cameron
Abstract:: The dc conductivity of single crystals of vanadium pentoxide was measured in the three crystallographic directions. The temperature range examined was -165°C to +25°C. The activation energy of the conduction process was isotropic and found to be .56 ev. The conductivity was anisotropic. Measurements of the Hall effect were attempted...

Electrical conductivity of additively colored potassium chloride crystals

Creator:: Seevers, Robert Edward
Abstract:: When the dc conductivities of various pure KC1 crystals were compared it was found that crystals grown under an HC1 atmosphere, from salt purified by ion exchange, exhibited lower knee temperatures than any of the crystals studied. These knee temperatures were found to be approximately 350°C. From this the total...

Some electrochemical properties of the vanadium pentoxide electrode

Creator:: Newby, Kenneth Russ
Abstract:: Vanadium pentoxide single crystals were grown from the melt. These crystals were made the cathode in an electrolytic cell and the polarization and recovery of the electrode were studied under a variety of experimental conditions. A study of the electrode potential versus that of the standard hydrogen electrode as a...

The reaction between O-ions and F centers

Creator:: Staible, Thomas Fredrick
Abstract:: The photochemical reaction between O⁻ ions and F centers was investigated. The activation energy was determined by the Arrhenius law to be 0.10 + 0.04 eV for temperature below 180°K. The diffusion of alpha centers towards the oxide ion was eliminated as the rate limiting step and the low trapping...

Optical and EPR investigations of the photochemistry of KCl:OH

Creator:: Bowen, Robert Clifford
Abstract:: The hydroxide ion as a substitutional defect in KC1 can be photo-dissociated at liquid nitrogen temperature by ultraviolet light. The photochemistry of this system was investigated by EPR and optical absorption methods. Theoretical calculations were also performed in an investigation of the KC1:OH system. The bleaching behavior of photochemically colored...
