Available in PDF, EPUB and Kindle. Book excerpt: The next generation of nuclear fission and fusion reactors depends upon the development of high performance structural materials. Silicon carbide (SiC) is being considered for a variety of nuclear reactor components because it possesses outstanding physical and chemical properties, including: high thermal conductivity, high temperature stability, chemical inertness, extreme hardness and small neutron capture cross-section. However, when exposed to energetic particles, SiC is observed to experience various radiation induced defects such as: vacancy clusters, dislocation loops and network dislocations at lower temperatures and swelling of the material causing voids/cavities at higher temperatures. Recent studies have shown nanostructured interfaces and nanoscale grains are more radiation damage tolerant. Polymer derived ceramics (PDCs) provide a unique route to develop SiC ceramics with nanostructural features that can help mitigate radiation defects. A novel class of SiC ceramics with controlled microstructures has been developed through tailoring of the molecular architecture of the starting precursor (allylhydridopolycarbosilane, Starfire® SMP-10). Nanostructural features in the form of graphene layers were incorporated via excess carbon from the addition of divinylbenzene (0-5 wt%) to the liquid SMP-10. It was observed that with increasing concentration of carbon, the 6H SiC (hexagonal) phase formed at the expense of 3C SiC (cubic). The utilization of PDCs also made possible the addition of sintering additives at the molecular level through a hydroboration reaction of SMP-10 with decaborane. This allowed the boron additives to be contained within the SiC grains, as opposed to on the grain boundaries, as is observed in traditional ceramic processing. Finally, these materials were irradiated using ion accelerator facilities located at the Environmental Molecular Sciences Laboratory at the Pacific Northwest National Laboratory. AFM results indicate that utilizing PDC processing routes vs. traditional ceramic routes yielded a significant decrease in the amount of swelling from point defect accumulation due to radiation bombardment. This research contributes to current priorities in designing materials for the next generation of nuclear power plants that are anticipated to have minimal waste, decreased risk of proliferation and increased accident damage tolerance.

Book excerpt: It has been three decades since the last significant book was published on SiC ceramics (other than those books that specifically focus on SiC semiconductors). Thirty years has been a long time in the world of SiC ceramics. In the early 1990s, SiC was still a relatively obscure ceramic even within the materials community, prominent only as an industrial abrasive (carborundum), and a refractory (Chapter 7). This has all changed dramatically in the 21st century. For example, As a semiconductor, SiC greatly surpasses silicon in performance, especially in high-power systems. Its market penetration since its launch in 2001 has been exponential. Single-crystal SiC semiconductors are covered in Chapter 3 Millions of military and paramilitary personnel have globally been protected with lightweight SiC body armour, since the late 1990s. Body armour is covered in Chapters 4 and 5 SiC–SiC is a composite material close to commercialization that makes possible high-temperature load-bearing applications hitherto only able to be hypothesized: from ultra-high-temperature jet turbine blades to advanced nuclear fuel encapsulation, the possibilities are very promising. Aerospace applications are covered in Chapter 9 Other key areas that are addressed are blast-resistant SiC vehicle/vessel armour in Chapter 8 and wear-resistant SiC ceramics in Chapter 6 Silicon Carbide Ceramics will be an essential reference resource for academic and industrial researchers and materials scientists and engineers working in ceramic materials for the semiconductor, defence, aerospace, wear resistance and refractory fields Presents an extensive review of the history, production and properties of SiC ceramics, including their characterization and applications Discusses classical and state-of-the-art sintering technologies for SiC ceramics Focuses on the future of ceramic manufacturing and advanced ceramic additive technologies

Available in PDF, EPUB and Kindle. Book excerpt: To date, many types of polymer-derived ceramic fibers have been developed all over the world. Of these, SiC fibers synthesized from polycarbosilane and its derivatives have achieved the highest heat-resistance along with their excellent mechanical properties. Using these type of SiC fibers for the ceramic matrix composite materials, both high-temperature strength and light weight have been achieved. Therefore, these fibers have attracted a great deal of attention in the field of next-generation aerospace engine, nuclear applications, and so on. Furthermore, several types of functional ceramic fibers with surface gradient structures have been developed using derivatives of polycarbosilane. This book summarizes the historical viewpoint of polymer-derived ceramic fibers, basic information (production process, fine structures, physical properties, and so forth) about them, and their applications. It also presents prospects of future inorganic fibers.

Available in PDF, EPUB and Kindle. Book excerpt: Discovered by Edward G. Acheson about 1890, silicon carbide is one of the oldest materials and also a new material. It occurs naturally in meteorites, but in very small amounts and is not in a useable state as an industrial material. For industrial require ments, large amounts of silicon carbide must be synthesized by solid state reactions at high temperatures. Silicon carbide has been used for grinding and as an abrasive material since its discovery. During World War II, silicon carbide was used as a heating element; however, it was difficult to obtain high density sintered silicon carbide bodies. In 1974, S. Prochazka reported that the addition of small amounts of boron compounds and carbide were effective in the sintering process to obtain high density. It was then possible to produce high density sintered bodies by pressureless sintering methods in ordinary atmosphere. Since this development, silicon carbide has received great attention as one of the high temperature structural ceramic materials. Since the 1970s, many research papers have appeared which report studies of silicon carbide and silicon nitride for structural ceramics.
