Pressureless melt infiltrated non-oxide ceramic-metal composites
(2009)
In the present study highly dense (open porosity > 1 %), light-weight (d ? 2.85 g/cm3) and Al4C3-free non-oxide ceramic-metal composites were produced at comparatively low temperatures (? 1250°C) by pressurless melt ...
Rapid Pyrolysis of Olive Residue. 2. Effect of Catalytic Upgrading of Pyrolysis Vapors in a Two-Stage Fixed-Bed Reactor
(American Chemical Society, 2009)
The upgrading of the rapid pyrolysis vapors was performed using various catalysts (clinoptilolite (a natural zeolite, NZ), ZSM-5, H-Y) with catalyst/feed ratios of 0.05, 0.1, 0.15, 0.20, and 0.25 in the catalyst bed ...
Evaluating vibration assisted vacuum infusion processing of hexagonal boron nitride sheet modified carbon fabric/epoxy composites in terms of interlaminar shear strength and void content
(Elsevier Sci LTD, 2016)
The results of an investigation of the effect of voids on the interlaminar shear strength (ILSS) of carbon fabric/epoxy composites consolidated from fabric preforms containing hexagonal boron nitride sheets (h-BNSs) were ...
Tailoring thermal conductivity of silicon/germanium nanowires utilizing core-shell architecture
(Amer Inst Physics, 2016)
Low-dimensional nanostructured materials show large variations in their thermal transport properties. In this work, we investigate the influence of the core-shell architecture on nanowire (1D) thermal conductivity and ...
Image analysis of sulfate attack on hardened cement paste
(Elsevier Sci LTD, 2008)
This paper presents an investigation conducted on the sodium sulfate resistance of Portland cements with various C(3)A contents, and on two blended cements produced by replacing 40% Of low C3A cement with fly ashes having ...
A novel approach for synthesis of monticellite based bioactive ceramic powders from boron derivative waste
(Elsevier Science BV, 2017)
Monticellite bioactive ceramics have a high usage potential as bone graft substitutes due to their superior mechanical properties compared to hydroxyapatite and excellent bioactivity. Turkey has almost 72% of the global ...
Analytical transmission electron microscopy observations on the stability of TiCN in electrically conductive alpha-beta SiAlON/TiCN composites
(Elsevier Sci LTD, 2014)
Coating of alpha-beta SiAlON granules with TiCN powder led to a continuous 3D electrically conductive network formation. Here, the stability of TiCN grains following gas pressure sintering (GPS) and its effect on the ...
Effect of the milling process on the properties of CoFe2O4 pigment
(Elsevier Sci LTD, 2013)
In this study, CoFe2O4 pigments were synthesised using both co-precipitation and conventional ceramic methods. Pigment particles prepared using the conventional ceramic method were subsequently milled to submicron size. ...
Structural insights on understanding the cubic phase stabilization mechanism of sol-gel synthesized Li7-3xAlxLa3Zr2O12 (x=0-0.4) - The effect of ZrOCl2 and ZrO(NO3)(2)
(Elsevier Sci LTD, 2018)
Stabilization of cubic Li7La3Zr2O12 phase, one of the most promising solid electrolytes for Li-ion batteries, has been extensively studied in terms of various stabilizer additions in solution-based systems. However, different ...
Experimental and finite element study of the thermal conductivity of alpha-SiAlON ceramics
(Blackwell Publishing, 2007)
The thermal conductivity of monolithic Y-Sm/alpha-SiAlON was evaluated using experimental data and finite element analysis. The thermal diffusivities of Y, Y-Dy, and Y-Ce/alpha-SiAlON ceramics were also investigated ...
