Flextensional composite transducers: Designing, fabrication and application
(Springer, 2000)
The design, fabrication and application of flextensional composite transducers are summarized in this study. The moonie and cymbal type flextensional transducer consist of a ceramic driving element sandwiched between two ...
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 ...
Thermal stability of rare earth densified ?-sialon ceramics
(1997)
Typical ?-sialon and mixed ?-ß sialon starting compositions were densified by either hot pressing or pressureless sintering using the oxides of Yb, Dy, Sm and Nd. The resulting materials were heat-treated at 1450°C for up ...
Preparation of multiple-cation alpha-SiAlON ceramics containing lanthanum
(Amer Ceramic Soc, 1999)
Until recently, it was accepted that Ce3+ cations, with an ionic radius (r) of 1.03 Angstrom, were too large to form an alpha-SiAlON structure. However, more-recent studies have shown that cerium cations can be incorporated ...
Preparation of multiple-cation ?-SiAlON ceramics containing lanthanum
(1999)
Until recently, it was accepted that Ce 3+ cations, with an ionic radius (r) of 1.03 Å, were too large to form an ?-SiAlON structure. However, more-recent studies have shown that cerium cations can be incorporated into ...
Lichens of the Akşehir District (Konya)
(1998)
Eighty-nine lichen species belonging to 33 genera from Akşehir District of Kenya were determined. Staurothele frustulenta Vainio is a new record for the lichen flora of Turkey.
Effect of starting Si3N4 powder type and sintering conditions on the grain morphology of ?-SiAlON ceramics
(2002)
Nitrogen rich neodymium-ytterbium containing multi-cation ?-sialon starting compositions have been prepared by gas pressure sintering using "conventional" ?-Si3N4 or plasma produced ß-Si3N4 powder. The effect of ?-SiAlON ...
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 ...
