Book excerpt: Liquid phase sintering is used to densify silicon carbide based ceramics using a compound comprising a rare earth oxide and aluminum oxide to form liquids at temperatures in excess of 1600.degree. C. The resulting sintered ceramic body has a density greater than 95% of its theoretical density and hardness in excess of 23 GPa. Boron and carbon are not needed to promote densification and silicon carbide powder with an average particle size of greater than one micron can be densified via the liquid phase process. The sintered ceramic bodies made by the present invention are fine grained and have secondary phases resulting from the liquid phase.

This book was released on 2017-06-29 with total page 693 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In the past few years there has been rapid growth in the activities involving particulate materials because of recognized advantages in manufacturing. This growth is attributed to several factors; i) an increased concern over energy utilization, ii) a desire to better control microstructure in engineermg materials, iii) the need for 1mproved material economy, iv) societal and economic pressures for higher productivity and quality, v) requirements for unique property combinations for high performance applica tions, and vi) a desire for net shape forming. Accordingly, liquid phase sintering has received increased attention as part of the growth in particulate materials processing. As a consequence, the commercial applications for liquid phase sintering are expanding rapidly. This active and expanding interest is not well served by available texts. For this reason I felt it was appropriate to write this book on liquid phase sintering. The technology of liquid phase sintering IS quite old and has been in use in the ceramics industry for many centuries. However, the general perception among materials and manufacturing engineers is that liquid phase sintering is still a novel technique. I believe the diverse technological appli cations outlined in this book will dispel I such impressions. Liquid phase. sintering has great value in fabricating several unique materials to near net shapes and will continue to expand in applications as the fundamental attrib utes are better appreciated. I am personally involved with several uses for liquid phase sintering.
Download or read book Thermal Processing of Injection Molded Silicon Carbide written by Richard E. Chinn and published by . This book was released on 2015 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon carbide is an important and versatile nonoxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding--removal of organic additives--is the rate-limiting step in PIM. Sintering aids enable densification of sintered powders, especially in the absence of applied pressure during sintering. Thermal Processing of Injection-Molded Silicon Carbide presents a study of the effects of GMM, debinding, sintering aids and sintering on two size distributions of PIM [alpha]-SiC with 5% each of Y2O3 and AlN as sintering aids. The use of 10% 20-nm particles, i.e., a bimodal size distribution, to increase the packing density of the green bodies was found to have a small effect on the rate of debinding, the liquid-phase sintering (LPS) precipitates, the microstructural development and the mechanical properties of SiC compared to the conventional monomodal size distribution, where D50 = 0.7 [micro]m. The nanoparticles and debinding methods did have a strong effect on the feasibility of GMM on SiC. The nanoparticles, debinding methods and GMM in combination significantly affected the sinterability of SiC. The rates and effects of solvent debinding and thermal debinding were measured and compared by various kinetic models. The catalytic effect of the bimodal SiC, if any, was small compared to PIM SiC with monomodal particles. The activation energy for thermal debinding was similar to that of solvent debinding. Too rapid of debinding by either method was detrimental to sintering in the form of fracture in the green body by residual stress. The debinding mechanism shifted from surface dissolution to bulk diffusion as the solvent debinding progressed. Changes in thermal debinding mechanisms were also noted as a function of heating rate. Thermal debinding was problematic in PIM bars with a large characteristic diffusion path length [psi], which led to fractures during sintering. Weak particle bonding and uncontrolled grain growth were observed in some cases after thermal debinding, and attributed to dissolution of aluminum in SiC, excess oxidation of the SiC and premature decomposition of polypropylene. Solvent debinding was less stressful, but not without fractures in some instances due to the swelling of the wax as it dissolved. Monomodal SiC was much more amenable to GMM than bimodal, whether solvent or thermally debound. The GMM swarf adhered to the monomodal more than to bimodal, even after the wax holding the swarf to the substrate was dissolved. The bimodal SiC had about one percentage point better densification than the monomodal. The grain size, precipitate content and Knoop hardness were about the same for monomodal and bimodal, whether solvent or thermally debound, with or without GMM, except in the case of thermally dewaxed bimodal SiC.
