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.

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.

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.

This book was released on 2015-07-23 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, improvements in the heat resistance of silicon nitride (Si3N4) ceramics using grain boundary control and in plasticity at high temperatures using grain size control in order to reduce the cost of shaping Si3N4 are described. The heat resistance of Si3N4 is improved by mixing a slight amount of sintering additive as an impurity into the original material powder. The author presents his findings on the high heat resistance of Si3N4. The author also develops a new fabrication method for Si3N4 nano-ceramics that produces high plastic formability. The method developed offers two improved points in grinding and sintering processes. The author found that the plastic formability of Si3N4 nanoceramics is dependent on load stress; the results of his research are detailed in this book.
