Available in PDF, EPUB and Kindle. Book excerpt: Silicon carbide (SiC) whiskers have great potential, some already realized, in reinforcing ceramic matrix composites to give significant improvements in toughness and strength. Los Alamos has been developing the vapor-liquid-solid (VLS) process to grow single crystal BETA-SiC fibers having relatively few defects and diameters of from 3 to 5 .mu.m and lengths up to 100 mm. These whiskers have superb mechanical properties-strengths up to 16 GPa (2.3 Msi) and elastic modulus of 580 GPa (84 Msi) - and should have excellent stability at high temperatures. Two basic synthesis routes were investigated: 1) in situ SiO generation and 2) external gaseous Si source. Process 1) had a much more extensive prior developmental history and has been developed at Los Alamos to the point where significant and reproducible yields of prime whiskers can be obtained and scaleup could be considered. What we have learned about this process and its product will be the subject of this paper. 14 refs., 17 figs., 31 tabs.
Book Synopsis SYNTHESIS AND CHARACTERIZATION OF SILICON CARBIDE WHISKERS AND THEIR APPLICATION IN SILICON NITRIDE MATRIX COMPOSITES (SILICON CARBIDE, SILICON NITRIDE). by : Liya Wang

This book was released on 1991 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Type C SiC whiskers showed a more obvious toughening effect for Si$\sb3$N$\sb4$ ceramics than the commercial Tokamax SiC whiskers. This might be due to the effect of interfacial bonding and/or the effect of the morphology and size of the whiskers.

Book Synopsis Carbide, Nitride and Boride Materials Synthesis and Processing by : A.W. Weimer
Download or read book Carbide, Nitride and Boride Materials Synthesis and Processing written by A.W. Weimer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbide, Nitride and Boride Materials Synthesis and Processing is a major reference text addressing methods for the synthesis of non-oxides. Each chapter has been written by an expert practising in the subject area, affiliated with industry, academia or government research, thus providing a broad perspective of information for the reader. The subject matter ranges from materials properties and applications to methods of synthesis including pre- and post-synthesis processing. Although most of the text is concerned with the synthesis of powders, chapters are included for other materials such as whiskers, platelets, fibres and coatings. Carbide, Nitride and Boride Materials Synthesis and Processing is a comprehensive overview of the subject and is suitable for practitioners in the industry as well as those looking for an introduction to the field. It will be of interest to chemical, mechanical and ceramic engineers, materials scientists and chemists in both university and industrial environments working on or with refractory carbides, nitrides and borides.

Download or read book Silicon Carbide Ceramics—1 written by S. Somiya and published by Springer Science & Business Media. This book was released on 1991-08-31 with total page 320 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.

Download or read book Application of Artificial Intelligence Control to the Vapor-liquid-solid Silicon Carbide Whisker Process written by and published by . This book was released on 1989 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon carbide whiskers have excellent mechanical and chemical properties, making them very desirable as a reinforcement for structural ceramic and other composite materials. Los Alamos has developed a laboratory-scale batch process for producing very high quality SiC whiskers by the vapor-liquid-solid (VLS) method which is an active candidate for technology transfer involving significant scale-up. The process, however, involves quite complex chemical/physical and parametric relationships and has not as yet lent itself successfully to modeling. An expert computer system was therefore developed to facilitate the transfer of this technology to industry. Optimum conditions were determined by relating the many process parameters to product results to establish a set of rules for running the process. These are incorporated in a two-phase expert system designed to guide inexperienced users. In Phase 1, an expert consultant program provides the user with information that enables him to set up the run. This information is incorporated into the rule base that makes up Phase 2 -- the control system. At present, the operator functions as the controller by responding to the decisions of the expert system; automation can be added later. 13 refs., 16 figs.
