Book Description
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 Description
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.

Carbide, Nitride and Boride Materials Synthesis and Processing
Author: A.W. Weimer
Publisher: Springer Science & Business Media
ISBN: 9400900716
Category : Technology & Engineering
Languages : en
Pages : 675
Book Description
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.
