Production and characterisation of granulated frit to achieve anorthite based glass-ceramic glaze
(Elsevier Sci LTD, 2015)
For the development of matt-transparent glass ceramic coating applied on the porcelain tile, the CaO-Al2O3-SiO2 system was studied. Sinterization and devitrification behavior of granulated frits and viscosity change with ...
Catalytic pyrolysis of biomass: Effects of pyrolysis temperature, sweeping gas flow rate and MgO catalyst
(Pergamon-Elsevier Science LTD, 2010)
Cotton seed, as a biomass source, is pyrolysed in a tubular fixed-bed reactor under various sweeping gas (N(2)) flow rates at different pyrolysis temperatures. In the non-catalytic work, the maximum bio-oil yield was ...
Spark plasma sintering of Co-WC cubic boron nitride composites
(Elsevier Science BV, 2009)
25 vol.% cubic boron nitride (cBN) added tungsten carbide (WC) powders containing 6 wt.% Co (WC-6Co) were densified by spark plasma sintering (SPS) technique under different experimental conditions and the effect of cBN ...
Sr2+-Mg2+-doped SiAlON ceramics
(Blackwell Publishing, 2006)
In the present work, multi-cation-doped (Sr2+-Mg2+) SiAlON ceramics were investigated. MgO and SrO were used in 100:0 and 50:50 molar ratios. The mixture was sintered at 1800 degrees and 1830 degrees C for 1 h in a gas ...
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 ...
