Book Description
An investigation of the compatibility of molten uranium dioxide with tungsten, tantalum, tantalum diboride, tantalum carbide and hafnium carbide was conducted to indicate combinations that may be useful in nuclear reactors that are to operate at temperatures above the melting point of uranium dioxide, 5000 F. The evaluations were conducted at a test temperature of 52200 F for a period of 15 minutes in a high-purity argon atmosphere. One compatibility test of molten uranium dioxide with tungsten was conducted at 55000 F. The tests were performed with the refractory material in the form of a crucible that contained a uranium dioxide charge. Crucible cross sections were studied after testing, and the degree of reaction between uranium dioxide and the various crucible materials was judged by the use of X-ray diffraction analysis, metallographic examination, microhardness measurements, and electron-beam microanalysis.

Ultra-High Temperature Materials II
Author: Igor L. Shabalin
Publisher: Springer
ISBN: 9402413022
Category : Technology & Engineering
Languages : en
Pages : 755
Book Description
This exhaustive work in three volumes and over 1300 pages provides a thorough treatment of ultra-high temperature materials with melting points over 2500 °C. The first volume focuses on Carbon and Refractory Metals, whilst the second and third are dedicated solely to Refractory compounds and the third to Refractory Alloys and Composites respectively. Topics included are physical (crystallographic, thermodynamic, thermo physical, electrical, optical, physico-mechanical, nuclear) and chemical (solid-state diffusion, interaction with chemical elements and compounds, interaction with gases, vapours and aqueous solutions) properties of the individual physico-chemical phases of carbon (graphite/graphene), refractory metals (W, Re, Os, Ta, Mo, Nb, Ir) and compounds (oxides, nitrides, carbides, borides, silicides) with melting points in this range. It will be of interest to researchers, engineers, postgraduate, graduate and undergraduate students alike. The reader is provided with the full qualitative and quantitative assessment for the materials, which could be applied in various engineering devices and environmental conditions at ultra-high temperatures, on the basis of the latest updates in the field of physics, chemistry, materials science and engineering.
