Lanthanum titanate (La2Ti2O7) as an interphase material in alumina (Al2O3) based composites
(Trans Tech Publications LTD, 2004)The aim of this research is to fabricate and characterize alumina (Al2O3) / lanthanum titanate (La2Ti2O7) laminate ceramic composites. The interfacial bond between oxide laminates has a critical effect on the final mechanical ... -
Joining of SiAlON ceramics to pyrex glass
(Belgian Ceramic Society, 2004)In the present study, pressureless joining of gas pressure sintered (alpha-beta)-SiAlON ceramics to pyrex glass was investigated. Preoxidized SiAlON ceramics were used to enhance wettability and provide chemical compatibility ... -
Investigation of sanitaryware scrap behaviour in terracotta bodies
(Trans Tech Publications LTD, 2004)In this paper, an investigation into a potential use of unfired body scrap from a local sanitaryware manufacturer in commercial terracotta production was presented. Experiments were achieved under laboratory conditions by ... -
Characterisation of dorylaion (Turkey) pottery sherds from Hittite period
(Trans Tech Publications LTD, 2004)In this study, representative samples were taken from eleven pottery sherds of Hittite period recovered during the archaeological excavations of different years in the ancient city Dorylaion, which is nowadays called as ... -
Uses of basalt in floor tile
(Trans Tech Publications LTD, 2004)Basalt is an igneous rock composed primarily of calcic plagioclase and pyroxene, with or without olivine. In this study, basalt was added to a standard ceramic floor tile body composition in different proportions ranging ... -
An investigation into bloating behaviour of bone China body during biscuit firing
(Trans Tech Publications LTD, 2004)Amongst many studies on the textural, mineralogical and physical changes during biscuit firing of whiteware bodies, this paper attempts to investigate the bloating behaviour of a commercial bone china body during biscuit ... -
Applications of calcium phosphate based antibacterial ceramics on sanitary and tile wares
(Trans Tech Publications LTD, 2004)In this study, metal cation consisting calcium phosphate based antibacterial ceramic powders were synthesized with wet chemical technique. The developed antibacterial powder was added to the glaze composition of the ceramic ... -
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 ... -
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 ... -
Fundamentals for optimization of binding for high refractory mullite products
(Trans Tech Publications LTD, 2004)Properties of the binder matrix affect the quality of the refractory. Better qualities are possible if the binding is optimum. Mechanical properties, thermal shock resistance, creep and corrosion behaviour of the mullite ... -
Materials for high performance cymbal transducers
(Springer, 2004)The effects of materials on the performance of the cymbal-type flextensional transducers were investigated under in-air and water-loaded conditions by finite element analysis (FEA) methods. At the initial stage, FEA and ... -
