Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program is to develop a process for making shaped silicon carbide based ceramic materials with reduced microstructural flaw size by in situ reaction of silicon with fine, ultra-uniform pored carbon skeletons that are produced from liquid polymer solutions without particulate additions. Subsidiary objectives are: (1) delineation of the maximum section size producible while maintaining microstructural uniformity; (2) production of microstructures with characteristic features reduced from the current level of approximately 5-10 microns to the level of 1 micron or less; (3) characterization of microstructure, corresponding strength levels, and statistical uniformity; and (4) delineation of dimensional tolerances and surface finish that can be held during processing without finished machining. Very uniform and reproducible carbon skeletons have been produced and modified to provide for easy siliconization without extensive grain coarsening or formation of silicon veins and/or lakes have been achieved from 1 cm thick samples of carbon skeleton with particle size of 3.2 microns and pore size of 1.9 micrometers. The siliconized material has a maximum grain size of

Book excerpt: A program is underway to develop a process for making shaped silicon carbide base structural ceramics with reduced microstructural flaw size by in situ reaction of silicon with fine, ultra-uniform pored carbon skeletons that are produced from liquid polymer solutions without particulate additions. Thus far, very uniform carbon skeletons in two pore sizes (2.5 and 0.27 microns) have been produced and siliconized. Very uniform samples of approx 1 cm cross section have been produced in a silicon carbide material of approx 5 microns average size. Limited regions of material with carbide size less than 1 micron have also been produced. (Author).

Download or read book Silicon Carbide Ceramics 1 written by S. Somiya and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 300 pages. 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.

Book excerpt: Treatise on Materials Science and Technology, Volume 29: Structural Ceramics presents an overview of structural ceramics. This book begins with a survey of potential uses, designs, and barriers of particular types of structural ceramics. The silicon carbide family, silicon nitride and sialon family, and transformation toughened ceramics are discussed in detail, followed by an analysis of the various processing routes of each family of structural ceramics. This publication concludes with a review of the tribology of structural ceramics, considering many applications for structural ceramics in heat engines and other machinery that involve moving parts which must often resist wear or erosion. This volume is recommended for engineers, scientists, and researchers concerned with structural ceramics.

Available in PDF, EPUB and Kindle. Book excerpt: The last 30 years have seen a steady development in the range of ceramic materials with potential for high temperature engineering applications: in the 60s, self-bonded silicon carbide and reaction-bonded silicon nitride; in the 70s, improved aluminas, sintered silicon carbide and silicon nitrides (including sialons); in the 80s, various toughened Zr0 materials, ceramic matrix composites reinforced with silicon 2 carbide continuous fibres or whiskers. Design methodologies were evolved in the 70s, incorporating the principles of fracture mechanics and the statistical variation and time dependence of strength. These have been used successfully to predict the engineering behaviour of ceramics in the lower range of temperature. In spite of the above, and the underlying thermodynamic arguments for operations at higher temperatures, there has been a disappointing uptake of these materials in industry for high temperature usc. Most of the successful applications are for low to moderate temperatures such as seals and bearings, and metal cutting and shaping. The reasons have been very well documented and include: • Poor predictability and reliability at high temperature. • High costs relative to competing materials. • Variable reproducibility of manufacturing processes. • Lack of sufficiently sensitive non-destructive techniques. With this as background, a Europhysics Industrial Workshop sponsored by the European Physical Society (EPS) was organised by the Netherlands Energy Research Foundation (ECN) and the Institute for Advanced Materials of the Joint Research Centre (JRC) of the EC, at Petten, North Holland, in April 1990 to consider the status of thermomechanical applications of engineering ceramics.

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
