Download or read book The Entropy and Low Temperature Heat Capacity of Neptunium Dioxide written by Edgar F. Westrum and published by . This book was released on 1952 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The heat capacity of a two-gram sample of neptunium dioxide was determined from 10 to 315 degrees K in an adiabatic calorimeter. At 298.16 degrees K, the molal entropy and enthalpy calculated from the heat capacity data are 19.19 (plus or minus) 0.1 cal degree (exp -1) and 2770 (plus or minus) 15 cal, respectively. A pronounced hump was found in the heat capacity curve of neptunium dioxide at 25.3 degrees K similar to that found by Long, Jones, and Gordon in uranium dioxide at 28.6 degrees K. This anomaly in the heat capacity is suggestive of a cooperative phenomenon and is attributed to the incidence of antiferromagnetism below the temperature of the maximum in the heat capacity. A calorimeter for gram-scale samples and a modification of the cryostat design of Ruehrwein and Huffman so as to employ only liquid helium and liquid nitrogen as refrigerants are described.

Available in PDF, EPUB and Kindle. Book excerpt: Unlike earlier books in this series, this review describes the selection of chemical thermodynamic data for species of two elements, neptunium and plutonium. Although this came about more by circumstance than design, it has allowed for a more consistent approach to chemical interpretation than might have occurred in two separate treatments. It has also drawn attention to cases where the available data do not show expected parallels, and where further work may be useful to confirm or refute apparent differences in the behaviour of neptunium and plutonium.

Book excerpt: The low-temperature heat capacity behavior of PuO/sub 2/ was found to be anomalous and irreproducible, changing slightly after every one of seven liquid helium coolings. Data obtained from a second series of liquid helium coolings, made after refiring three of four original FuO/sub 2/ wafers in air, were consistent with the last run of the first series. The final low-temperature heat capacity vs temperature curve was more like that reported for ThO/sub 2/ than it was for similar curves reported for UO/sub 2/ and NpO/sub 2/. A least squares equation relating heat capacity and temperature is given for the low-temperature region. Values of heat capacity, entropy, and enthalpy are listed for several temperatures. (auth).

Download or read book Update on the Chemical Thermodynamics of Uranium Neptunium Plutonium Americium and Technetium written by R. Guillaumont and published by . This book was released on 2003-11-04 with total page 976 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is part of the series on "Chemical Thermodynamics", published under the aegis of the OECD Nuclear Energy Agency, and updates and expands the thermodynamic data on inorganic compounds and complexes of uranium, neptunium, plutonium, americium and technetium contained in the previous volumes of the series. A review team, composed of seven internationally recognized experts, has critically reviewed during five years all the scientific literature containing chemical thermodynamic information for the above mentioned systems that has appeared since the publication of the earlier volumes. The results of this critical review carried out following the Guidelines of the OECD NEA Thermochemical Database Project have been documented in the present volume, which contains new tables of selected values for formation and reaction thermodynamical properties and an extensive bibliography.
Download or read book Progress in International Research on Thermodynamic and Transport Properties written by Eric F. Lype and published by Academic Press. This book was released on 2013-10-22 with total page 773 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in International Research on Thermodynamic and Transport Properties covers the proceedings of the 1962 Second Symposium by the same title, held at Purdue University and the Thermophysical Properties Research Center. This symposium brings together theoretical and experimental research works on the thermodynamic and transport properties of gases, liquids, and solids. This text is organized into nine parts encompassing 68 chapters that cover topics from thixotropy to molecular orbital calculations. The first three parts review papers on theoretical, experimental, and computational studies of the various aspects of thermodynamic properties. These parts discuss the principles of phase equilibria, throttling, volume heat capacity, steam, volumetric behavior, enthalpy, and density. The subsequent part highlights the theoretical evaluations of transport properties, such as viscosity, diffusion, and conductivity, as well as the transport processes. These topics are followed by surveys of the theories in intermolecular forces and their applications. Other parts consider the measurement of thermal conductivity, viscosity, and radiation. The final parts examine the properties of ionized gases and non-Newtonian fluids. This book will prove useful to mechanical and chemical engineers.
