Microstructural evolution of mechanically alloyed and spark plasma sintered Ni-W alloy matrix composites
(2013)
Microstructural evolution of Ni(W) solid solution alloys fabricated via mechanical alloying (MA) of Ni - 30 wt.% W powders and spark plasma sintering (SPS) at 1000 C for 3 min were presented in this study. Due to contaminations ...
Characterization of lead glazed potteries from Smyrna (Izmir/Turkey) using multiple analytical techniques; Part I: Glaze and engobe
(Elsevier Sci LTD, 2014)
Eighteen lead glazed potsherds from the Ayasuluk region (Smyrna) were characterized in order to have detailed knowledge of their production technology. Micro-Raman and scanning electron microscopy (SEM) with the combination ...
Improvements on the mechanical properties and thermal shock behaviours of MgO-spinel composite refractories by ZrO2 incorporation
(Elsevier Sci LTD, 2012)
Microstructural features and improvements on the mechanical properties and thermal shock behaviours of MgO-spinel composite refractories with ZrO2 addition were examined. ZrO2 incorporation into MgO-spinel led to improvements ...
Densification and properties of in-situ synthesized ZrB2-SiC composities from ZrO2, B4C and SiC system
(Korean Assoc Crystal Growth, Inc, 2017)
Zirconium diboride-silicon carbide (ZrB2-SiC) ceramics were in-situ synthesized and densified by the spark plasma sintering (SPS) method using ZrO2, B4C and SiC as starting powders. Both synthesis and densification processes ...
Influence of post-annealing on electrical, structural and optical properties of vanadium oxide thin films
(2013)
Vanadium oxide thin films were grown onto quartz substrates using the pulsed DC reactive magnetron sputtering technique at room temperature and afterwards post annealed under vacuum conditions in the temperature range from ...
Effect of activators and calcination on luminescence properties of akermanite type phosphors
(Natl Inst Science Communication-Niscair, 2015)
Akermanite type Ca2MgSi2O7 phosphors activated with different types of rare earths have been synthesized through a solid state reaction method under weak reducing atmosphere and/or open atmosphere. The phase properties of ...
Preparation of nanosized tin oxide (SnO2) powder by homogeneous precipitation
(Elsevier Sci LTD, 2007)
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 ...
The third order nonlinear optical characteristics of amorphous vanadium oxide thin film
(Springer, 2011)
We studied the nonlinear absorptive characteristics (saturation intensity threshold and effective nonlinear absorption coefficients) and nonlinear refraction in a 50-nm-thick VO (x) thin amorphous film prepared by pulsed ...
Single Crystal Growth and Texturing of Lead-Based Piezoelectric Ceramics Via Templated Grain Growth Process
(World Scientific Publ Co Pte LTD, 2008)
In the field of high-performance piezoelectric materials, PMN-PT single crystals and textured ceramics have been attracting increased research interest for several years. On the other hand, the growth of single crystals ...
Investigation of porosity of ceramic tiles by means of image analysis method
(Korean Assoc Crystal Growth, Inc, 2014)
Amount, size and distribution of porosity are among the important factors which affect physical and mechanical properties of ceramic tiles. In this study, the effect of flux variation in porcelain tile recipes and different ...
