Book Description
Work presented includes: preparation of borides and carbides; low temperature heat capacity measurements on HfB2, HfC and hafnium metal; estimation of entropies at 298K for refractory diborides, nitrides, carbides, and oxides from high temperature heat content data; current status of heats of formation of the borides and carbides from oxygen and fluorine bomb calorimetry; and studies proving the feasibility of the matrix isolation technique for spectroscopy of high temperature molecules through studies on the Lithium halides. Status of electron diffraction, equilibria, and heat of solution studies of the hafnium and zirconium halides is presented. Kinetic studies completed on the oxidation and fluorination of the hafnium and zirconium carbides and diborides are presented in detail. From ac and dc electrical conductivity studies on tetragonal ZrO2, a model of the defect structure is devised and oxygen diffusion in ZrO2 is calculated. (Author).
Ultra-High Temperature Materials II
Author: Igor L. ShabalinPublisher: 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.
