Transmission electron microscopy studies of La2O3-doped alpha-SiAlON ceramics
(IOP Publishing LTD, 1999)
alpha-SiAlON is able to accommodate cations into its crystal structure if the cations are sufficiently small in size, thus helping to reduce the volume of the remnant grain boundary phase after processing. In this study, ...
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 ...
Effect of cobalt oxide and copper oxide additions to zinc-containing soft porcelain glazes
(Amer Ceramic Soc, 2001)
…
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 ...
Transmission electron microscopy of interfaces in structural ceramic composites
(Blackwell Science LTD, 1999)
Ceramic composites based either on a particulate, fibre or a lamellar architecture are potentially useful as damage-tolerant high-temperature engineering materials. The ability of the interfaces in such systems to deflect ...
High resolution transmission electron microscopy of grain boundaries between hexagonal boron nitride grains in Si3N4-SiC particulate composites
(Wiley-V C H Verlag GMBH, 2000)
High resolution transmission electron microscope observations of grain boundaries in hexagonal boron nitride in which adjacent grains are rotated with respect to one another about either <2 (1) over bar (1) over bar 0> or ...
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 ...
Mechanical properties of melt infiltrated boron carbide-aluminium composites
(Trans Tech Publications LTD, 2002)
Boron carbide (B4C)-aluminium (Al) composites were produced by melt infiltration of 2024-T3 series Al alloys into porous B4C compacts in the temperature range of 985 degrees -1370 degreesC under an inert atmosphere (Ar). ...
Chemical durability behaviour of bulk glasses in the SrO-Mn2O3Fe2O3-MgO-ZrO 2-SiO2 (SMFMZS) system
(2001)
It is known that the SrO-MgO-ZrO2-SiO2 (SMZS) system glasses with 40 weight % silica content seem to give a very high chemical endurance against highly alkaline solutions and can be recommended for the reinforcement of ...
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 ...
