Optimization of the optical properties of alpha-SiAlON through a decrease in starting powder size
(Elsevier Sci LTD, 2015)
In the present work, the effects of initial powder size on the sintering behavior and optical properties of Dy-alpha-SiAlON ceramics produced by the SPS technique are investigated. The powders were prepared using high ...
Magnetic Mesoporous Silica Nanocomposite for Biodiesel Production
(Polish Acad Sciences Inst Physics, 2017)
Ordered mesoporous silicas can be utilized as support because of having large surface area, tunable porosity, uniform pore size distribution, high thermal stability and modifiable properties. However, these materials ...
Effects of production method and space holder material on microstructure of porous titanium
(European Powder Metallurgy Association (EPMA), 2012)
The use of space holder particles is now a well-known and common method for production of porous titanium implants. It is possible to control porosity and pore structure by the use of a variety of spacer materials available. ...
Producing cordierite from local magnesium sources
(Trans Tech Publications LTD, 2004)
Cordierite ceramics were produced by using local magnesium sources. Mixtures were sintered at different temperatures to examine formation of cordierite. a-cordierite was formed as a major phase over 1150degreesC. High bulk ...
Spark plasma sintering of Si3N4-B4C composites
(Ceramic Soc Japan-Nippon Seramikkusu Kyokai, 2008)
In this study the production Of Si3N4-B4C Composites using spark plasma sintering technique was studied. This technique was preferred in order to minimize the reactions between starting constituents. Fully dense Si3N4 ...
Synthesis of nanosized tin oxide (SnO2) particles via homogeneous precipitation
(Trans Tech Publications LTD, 2004)
Synthesis of nanosized SnO2 ceramic particles via homogeneous precipitation was investigated as a function of processing parameters such as initial concentration and calcination temperature. Hydrous tin oxide was precipitated ...
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 ...
Spinel nitrides transparent ceramics
(Elsevier Sci LTD, 2015)
Aluminum oxy-nitride (AlON), a solid solution in the binary phase diagram of Al2O3-AlN, is a relatively new spinel type material. In the present study, the optimum sintering agent and sintering conditions of AlON were ...
Functionally graded SiAlON ceramics
(Elsevier Sci LTD, 2004)
Functionally graded SiAlON ceramics were developed by three different methods to improve the mechanical properties of SiAlONs; powder bed, rapid cooling and laminating. beta-SiAlON compacts were embedded in two different ...
Effect of the Powder Process Type on Dielectric and Leakage Current Characteristics of Flux Grown 94NBT-6BT Single Crystals
(IEEE, 2014)
In this study, 94NBT-6BT single crystals were grown by flux growth method using uncalcined and calcined 94NBT-6BT powder. Crystal structures and chemical composition of grown crystals were characterized by X-ray diffraction ...
