Wetting and non-wetting behaviour of silicon carbide grain boundaries
(Transtec Publications LTD, 1999)
Silicon carbide (SiC) grain boundaries have been observed to be free from intergranular films. On the basis of equilibrium film thickness calculations, it has been proposed elsewhere that because SiC has very high refractive ...
Capacitor discharge joining of silicon carbide based ceramics
(Trans Tech Publications LTD, 2002)
A capacitor-discharge joining technique has been successfully used to join oxide ceramics using thin metal foils. In this study, silicon carbide (SiC) ceramic joints and silicon carbide-titanium diboride (TiB2) composite ...
Hydrothermal synthesis of tabular perovskite particles
(Trans Tech Publications LTD, 2002)
Phase pure perovskite lead titanate and lead zirconate titanate powders were produced by hydrothermal synthesis. Reaction temperature and time are critical processing parameters for formation of phase-pure perovskite ...
Textured alumina ceramics by uniaxial pressing
(Trans Tech Publications LTD, 2002)
Highly textured, dense alumina ceramics were fabricated by a processing route which utilizes a mixture of Al metal powder, alumina powder, alumina platelet (template) particles and a liquid phase former. The process involves ...
Orientation-dependent equilibrium film thickness at interphase boundaries in ceramic-ceramic composites
(IOP Publishing LTD, 1997)
Theoretical considerations of the Hamaker constant for the interaction of two media across a third suggest that the highly anisotropic nature of the refractive indices of a medium such as h-BN will produce an orientation ...
Microstructural characterization of reactively sintered mullites
(Amer Ceramic Soc, 2000)
Mullite ceramics have been produced by reaction sintering of powders prepared using pseudoboehmite-colloidal silica and aluminum sulfate-colloidal silica mixtures. The microstructural development of these mullites was ...
Capacitor-discharge joining of oxide ceramics
(Amer Ceramic Soc, 1999)
A capacitor-discharge joining technique has been used to fabricate alumina-metal-alumina and zirconia-metal-zirconia joints using thin foils of aluminum, titanium, or amorphous AlxNiyYz alloys as interlayers. The technique ...
Boron nitride-silicon carbide interphase boundaries in silicon nitride-silicon carbide particulate composites
(Elsevier Sci LTD, 2002)
Interphase boundaries between SiC and h-BN grains in hot isostatically pressed Si3N4-SiC particulate composites made from both as-received powders and deoxidised powders, in which sub-micron size h-BN particles occur as a ...
The dependence of equilibrium film thickness on grain orientation at interphase boundaries in ceramic-ceramic composites
(Elsevier Science BV, 2000)
High-resolution transmission electron microscope observations of hexagonal boron nitride - 3C silicon carbide interphase boundaries suggest that where one or more phases is highly anisotropic, an orientation dependence on ...
New heat treatment methods for glass removal from silicon nitride and sialon ceramics
(Kluwer Academic Publ, 2000)
Sialon ceramics were discovered simultaneously (but independently) in late 1971 at Newcastle University and also at the Toyota Research Laboratories in Japan. During the 30 years since their original discovery, the Newcastle ...
