Book Description
The first comprehensive book to focus on ultra-high temperature ceramic materials in more than 20 years Ultra-High Temperature Ceramics are a family of compounds that display an unusual combination of properties, including extremely high melting temperatures (>3000°C), high hardness, and good chemical stability and strength at high temperatures. Typical UHTC materials are the carbides, nitrides, and borides of transition metals, but the Group IV compounds (Ti, Zr, Hf) plus TaC are generally considered to be the main focus of research due to the superior melting temperatures and stable high-melting temperature oxide that forms in situ. Rather than focusing on the latest scientific results, Ultra-High Temperature Ceramics: Materials for Extreme Environment Applications broadly and critically combines the historical aspects and the state-of-the-art on the processing, densification, properties, and performance of boride and carbide ceramics. In reviewing the historic studies and recent progress in the field, Ultra-High Temperature Ceramics: Materials for Extreme Environment Applications provides: Original reviews of research conducted in the 1960s and 70s Content on electronic structure, synthesis, powder processing, densification, property measurement, and characterization of boride and carbide ceramics. Emphasis on materials for hypersonic aerospace applications such as wing leading edges and propulsion components for vehicles traveling faster than Mach 5 Information on materials used in the extreme environments associated with high speed cutting tools and nuclear power generation Contributions are based on presentations by leading research groups at the conference "Ultra-High Temperature Ceramics: Materials for Extreme Environment Applications II" held May 13-19, 2012 in Hernstein, Austria. Bringing together disparate researchers from academia, government, and industry in a singular forum, the meeting cultivated didactic discussions and efforts between bench researchers, designers and engineers in assaying results in a broader context and moving the technology forward toward near- and long-term use. This book is useful for furnace manufacturers, aerospace manufacturers that may be pursuing hypersonic technology, researchers studying any aspect of boride and carbide ceramics, and practitioners of high-temperature structural ceramics.

Book Description
Ceramics are a versatile material, more so than is widely known. They are thermal resistant, poor electrical conductors, insulators against nuclear radiation, and not easily damaged, making ceramics a key component in many industrial processes. MAX Phases and Ultra-High Temperature Ceramics for Extreme Environments investigates a new class of ultra-durable ceramic materials, which exhibit characteristics of both ceramics and metals. Readers will explore recent advances in the manufacturing of ceramic materials that improve their durability and other physical properties, enhancing their overall usability and cost-effectiveness. This book will be of primary use to researchers, academics, and practitioners in chemical, mechanical, and electrical engineering. This book is part of the Research Essentials collection.

Book Description
Global population growth and tremendous economic development has brought us to the crossroads of long-term sustainability and risk of irreversible changes in the ecosystem. Energy efficient and ecofriendly technologies and systems are critically needed for further growth and sustainable development. While ceramic matrix composites were originally developed to overcome problems associated with the brittle nature of monolithic ceramics, today the composites can be tailored for customized purposes and offer energy efficient and ecofriendly applications, including aerospace, ground transportation, and power generation systems. The 9th International Conference on High Temperature Ceramic Matrix Composites (HTCMC 9) was held in Toronto, Canada, June 26-30, 2016 to discuss challenges and opportunities in manufacturing, commercialization, and applications for these important material systems. The Global Forum on Advanced Materials and Technologies for Sustainable Development (GFMAT 2016) was held in conjunction with HTCMC 9 to address key issues, challenges, and opportunities in a variety of advanced materials and technologies that are critically needed for sustainable societal development. This Ceramic Transactions volume contains a collection of peer reviewed papers from the 16 below symposia that were submitted from these two conferences Design and Development of Advanced Ceramic Fibers, Interfaces, and Interphases in Composites- A Symposium in Honor of Professor Roger Naslain Innovative Design, Advanced Processing, and Manufacturing Technologies Materials for Extreme Environments: Ultrahigh Temperature Ceramics (UHTCs) and Nano-laminated Ternary Carbides and Nitrides (MAX Phases) Polymer Derived Ceramics and Composites Advanced Thermal and Environmental Barrier Coatings: Processing, Properties, and Applications Thermomechanical Behavior and Performance of Composites Ceramic Integration and Additive Manufacturing Technologies Component Testing and Evaluation of Composites CMC Applications in Transportation and Industrial Systems Powder Processing Innovation and Technologies for Advanced Materials and Sustainable Development Novel, Green, and Strategic Processing and Manufacturing Technologies Ceramics for Sustainable Infrastructure: Geopolymers and Sustainable Composites Advanced Materials, Technologies, and Devices for Electro-optical and Medical Applications Porous Ceramics for Advanced Applications Through Innovative Processing Multifunctional Coatings for Sustainable Energy and Environmental Applications

Book Description
"Research into ultra high temperature materials has increased in recent years due to the need for material systems that can withstand the temperatures associated with hypersonic flight applications. ZrB2 and HfB2 are among the candidates for these extreme conditions. These diborides have melting temperatures that exceed 3000°C, the potential for strength retention at elevated temperatures, and moderate oxidation resistance when compared to high temperature carbides. However, diborides have often been reported to exhibit low strength and significant strength degradation by 1500°C; therefore, limiting their use at high temperatures ... This research focused on processing zirconium diboride (ZrB2) ceramics that exhibit improved mechanical performance and reduced impurity content. Three processing methods have been used to produce dense ZrB2 ceramics; conventional hot pressing, reactive hot pressing, and pressureless sintering"--Abstract, leaf iv.

Book Description
Tantalum carbide (TaC) belongs to a class of materials known as ultra-high temperatureceramics (UHTCs) with unique combinations of physical, chemical and electronic properties. The following study presents for the first time the morphologically controlled synthesis of TaC nanoparticles using a modified solvothermal method. X-ray diffraction revealed that highly crystalline TaC can be obtained with excellent phase purity. Doping by metallic species is shown to have significant impact on the final morphology of TaC nanoparticles. The shape selectivity and morphology evolution from round/irregular shapes to cubes and cuboctahedrons varies with the type of dopant, including Ni, Fe, Co, Y and Ni-Ti co-doping. Statistical abundance of over 80% particles with high-faceted morphologies were observed, significantly surpassing that of undoped samples (around 10%). Experimental interpretation was coupled by the Density Functional Theory (DFT) based calculation to probe the fundamental mechanisms responsible for the dopant-induced change in the growth habit of TaC nanoparticles. It was found that the major formation mechanisms include surface segregation of dopants, atomic orbital interaction between dopants and carbon, which caused the change in relative growth rate of facets. The probability of forming one type of faceted particles over another is governed by the surface energy distributions. The mechanisms and techniques explored herein are expected to be generally applicable to other transition metal-based ceramics thereby providing an unprecedented pathway towards the morphology tailoring of high-temperature materials. Principles of crystal growth and prior works for morphologically controlled synthesis of a variety of inorganic materials were also thoroughly reviewed.
