Double layer glaze applications for the vitrifies glazes and surface properties
(Trans Tech Publications LTD, 2004)Sanitaryware glazes are of the raw type and have zirconium silicate as an opacifier. Glaze compounds affect glaze properties such as mechanical strength, surface proper-ties etc. In this study, glazes were prepared in order ... -
Tailoring the Q of cymbal transducer
(Trans Tech Publications LTD, 2004)In general high Q is a desired property for transducer applications, which is the indication low loss. However for the underwater acoustic applications wide bandwidth is also a desired property. Therefore the Q values ... -
Electrophoretic deposition of ZnO thin film in aqueous media
(Springer, 2004)In thin films, controlled porous structures are desired for certain ceramic gas sensors. The aim of this study was to fabricate ZnO coated substrates starting with aqueous suspensions with electrophoretic deposition ... -
Size and material effects on cymbal transducer for actuator applications
(Taylor & Francis LTD, 2006)Flextensional cymbal pizocomposites have a number of applications as actuators, sensors, and transducers. In this study, the effect of the design parameters and materials on actuator performance were evaluated by Finite ... -
Pressing behaviour of spray dried alumina-zirconia granules
(Trans Tech Publications LTD, 2004)In this study, spray drying of alumina-zirconia slurries on a pilot scale, and their pressing behaviour were investigated. Slurries were prepared at 50 wt-% solid loading. An acrylic polymer emulsion, polyethylene glycol, ... -
Pressureless sintering of Al2O3-TiCN composites
(Trans Tech Publications LTD, 2004)A composition of 70 wt % Al2O3 + 30 wt % TiCN was prepared and pressureless-sintered at temperatures ranging from 1700 to 1840degreesC. In order to achieve densification, a powder bed was also employed. The resultant ... -
Electrophoretic deposition of ZnO
(Trans Tech Publications LTD, 2004)Electrophoretic phonemenon is applied in different parts of science. Electrophoretic Deposition (EPD) is effective, fast and controllable process for obtaining various thin or thick film layers. In this study application ... -
Production of alpha-beta SiAlON-TiN/TiCN composites by gas pressure sintering
(Belgian Ceramic Society, 2004)Due to the favorable properties possessed by novel alpha-beta SiAlONs, they are attractive materials for cutting tool applications. Such applications require materials with high hardness, high fracture toughness and high ... -
Application of syenite as a raw material and its effects on the physical characteristics of the ceramic structure of floor tile
(Trans Tech Publications LTD, 2004)Syenite has been used as a fluxing agent in floor tile ceramic compositions. The raw material of syenite has an important role to the regulation of furnace performances, due to its lowering of the melting point and its ... -
An experimental and theoretical examination of the effect of sulfur on the pyrolytically grown carbon nanotubes from sucrose-based solid state precursors
(Pergamon-Elsevier Science LTD, 2011)Multi-walled carbon nanotubes (MWCNTs) were synthesized through pyrolysis of the sulfuric acid-carbonized byproduct of sucrose. While the presence of sulfur in the reaction media has a key role in the formation and population ... -
Towards atomic scale engineering of rare-earth-doped SiAlON ceramics through aberration-corrected scanning transmission electron microscopy
(Pergamon-Elsevier Science LTD, 2011)Direct visualization of rare earths in alpha- and beta-SiAlON unit-cells is performed through Z-contrast imaging technique in an aberration-corrected scanning transmission electron microscope. The preferential occupation ... -
Incorporation of the transition metals (Cr and Fe) into beta-SiAlON crystal structure
(Elsevier Sci LTD, 2011)Outstanding properties for SiAlON ceramics can be obtained by tailoring the microstructure through alpha-SiAlON and beta-SiAlON phase content as well as a type of secondary phases. It is so far well known that while some ... -
