Refractory materials are used in several industries involving very aggressive environments, thus the number of chemical, thermal and physical properties required for a refractory material are high and diverse. In Refractory Materials: Characteristics, Properties and Uses, the authors suggest that the determination of the mineralogical phases amounts is an essential parameter for the design of new refractories matrix to have command over the desired properties and quality of the final product. The subsequent chapter may serve as a guide to the composition- and microstructure-based interpretation of experimental findings in refractory materials. Based on the concepts and refractory materials data provided in this book, taking into account the general issues concerning strength measurements, the reader should be able to realistically assess even such complex quantities as thermal shock resistance parameters. Next, a systematic joint study of the temperature dependences of the isobaric molar heat capacity CP(T) and the volume coefficient of thermal expansion β(T) of polyatomic solids was carried out on the example of refractory oxide ceramics: periclase, MgO, and corundum, Al2O3. Both ceramics have the widest practical applications and are considered as reference substances, which justifies their choice for research. In the closing chapter, the B-model is applied to a joint study of temperature dependences of the principal thermodynamic functions of the selected refractory oxide ceramics, namely, periclase, MgO, and corundum, Al2O3. Primarily, the isobaric molar heat capacity CP(T), the volume coefficient of thermal expansion β(T), and their correlation, β(CP), were investigated between T = 0 and the melting point Tm. Under the B-model control, mutually consistent calorimetric (change in the molar enthalpy, the molar entropy, the reduced thermodynamic potential) and dilatometric (the molar volume, the volume coefficient of thermal expansion) data were obtained and tabulated in the entire solid state range of the ceramics.

The book provides, in a compact format, basic knowledge and practically oriented information on specific properties of refractory materials, on their testing and inspection, and on interpretation of test results. Tables and illustrations are used to clarify fundamental concepts on a comparative basis. This pocket format manual provides an overview of the diverse range of modern refractories and their application-relevant properties. Its main feature is a series of practice-derived articles by well-known authors in the field on the various material groups and their characteristic property data. The content has deliberately been kept concise and instructive, abstracting and more detailed works are referenced.

An exploration of electric refractory materials, this book covers developments of blue light-emitting diodes using GaN-based nitrides for laser and high-temperature and -frequency devices. Electric Refractory Materials introduces growth and evaluation standards of films and bulk crystals, with consideration of band structure, surface electronic structure, and lattice vibrations. It also covers heat capacity and thermal conductivity, irradiation properties, and selective surfaces. Focusing on diamond material, the book examines its synthesis and characterization as well as its electrical, optical, and conductive properties. The book also discusses the use of silicon carbide, boron compounds, and other material used in electronic and light-emitting devices.

The first book since 1974 written by a steelmaking end user and refractory engineer Why do you pick the refractory you do? How do you choose? Where do you start the selection process? The answers to these questions must always take into account the balance of competing interests among operations, purchasing, and the suppliers. Refractory Material Selection forSteelmaking is the ultimate guide to finding ideal answers to these questions. By following the step-by-step instructions—paired with detailed explanations and full-color diagrams—readers will be able to critically select the materials that are most appropriate for them. This book considers: The goals of refractory selection What causes refractories to wear out The properties of refractories and their raw materials Specific refractory applications Key strategies used to procure refractories Tom Vert's 25 years of experience in steelmaking combined with a ceramic engineering background provide comprehensive information that will benefit anyone working with refractories in steelmaking or any other industry.

Materials covered include carbon, alloy and stainless steels; alloy cast irons; high-alloy cast steels; superalloys; titanium and titanium alloys; refractory metals and alloys; nickel-chromium and nickel-thoria alloys; structural intermetallics; structural ceramics, cermets, and cemented carbides; and carbon-composites.
