Book Description
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 with a dc and ac apparatus, but the signal was too low to be observed. However, an upper limit of 71 cm3/coulomb for the Hall coefficient was calculated, and the upper limit computed for the mobility was .4 cm2/volt sec. A model is proposed for the conduction mechanism. It suggests that the electrical conduction is a two -step process. The electron is ionized from a V4-oxygen-vacancy center and then moves through the lattice via polaron movement. This model accounts for the isotropy of the activation energy and also the anisotropy of the conductivity. In addition, the dielectric constant is calculated to be 25 assuming the proposed model.

Book Description
It was seven years ago this month when I had the pleasure of writing the Foreword to the Proceedings of the Eighth Conference on Thermal Conductivity hosted by TPRC/ Purdue University in 1968. Since then this Conference has developed to the point where one can say it has just entered a new phase. At its meeting in June 1975, the Board of Governors of the International Thermal Conductivity Conferences passed a resolution which formalizes two main policies that were felt to be desirable for a number of years, A key item of the resolution was for CINDAS/Purdue University to become the permanent Sponsor of the Conferences and in this capacity assist the Conferences in all matters which will result in the effective implementation of its goals and mission. In short, CINDAS will serve as a home base for the Conferences thus providing continuity and a permanent point of contact. CINDAS/Purdue University is pleased to accept this respons ibility as it is well within its mission to promote the advancement and dissemination of knowledge on thermophysica! properties of matter. A second important aspect of the Conference resolution was the establishment of a policy to publish the Proceedings of future conferences on a continuing and uniform basis effective with this, the Fourteenth Conference.

Book Description
Electroceramics, Materials, Properties, Applications, Second Edition provides a comprehensive treatment of the many aspects of ceramics and their electrical applications. The fundamentals of how electroceramics function are carefully introduced with their properties and applications also considered. Starting from elementary principles, the physical, chemical and mathematical background of the subject are discussed and wherever appropriate, a strong emphasis is placed on the relationship between microstructire and properties. The Second Edition has been fully revised and updated, building on the foundation of the earlier book to provide a concise text for all those working in the growing field of electroceramics. * fully revised and updated to include the latest technological changes and developments in the field * includes end of chapter problems and an extensive bibliography * an Invaluable text for all Materials Science students. * a useful reference for physicists, chemists and engineers involved in the area of electroceramics.
