Identification of Ti incorporation into beta-SiAlON crystal structure through transmission electron microscopy techniques
(Elsevier Sci LTD, 2012)
In this paper, we report the transmission electron microscopy (TEM) observations on the incorporation of Ti transition metal element into beta-SiAlON crystal structure in a bulk beta-SiAlON-TiN composite material. Considering ...
Formation of ?-SiAlON ceramics containing scandium
(2004)
?-SiAlON is able to accommodate cations into its crystal structure if the cations are sufficiently small in size, thus helping to reduce the volume of the remnant grain boundary phase after processing. Lutetium with an ...
Synthesis of the CeO2 based pigments by using enriched rare-earth oxides located at eskişehir kizilcaören region
(2004)
Pigments based on CeO2 structure are known to give various pink-orange and red brown colour in ceramic glazes. This type of pigments is prepared by high temperature calcination of CeO2 and Pr 6O11 with admixed rare-earth ...
A comparative study on few-layer graphene production by exfoliation of different starting materials in a low boiling point solvent
(Elsevier Science BV, 2017)
Three different graphite-based powders (expandable graphite and two different nano-graphite powders) were investigated as starting materials for an effective liquid phase exfoliation process in isopropyl alcohol (IPA). The ...
B-Phase solid solutions in Er- and Y-SiAlON glass-ceramics
(Springer, 2015)
Glasses with cation composition of M: Si: Al = 3.45:3:2 (where M = Er and Y) with varying nitrogen contents (0, 5, 8, 15 and 22 eq.%) have been prepared by ball milling in alcohol media. These Er-and Y-sialon glasses were ...
Size evolution of nanomagnetic particles and magnetotransport properties of (Co 90Fe 10) 20Ag 80 nanogranular films: Influence of Cu 80Ag 15Au 5 underlayer
(2012)
The influence of (Co 90Fe 10) 20Ag 80 film thickness and of Cu 80Ag 15Au 5 underlayer on nanomagnetic, magnetotransport and structural properties of (Co 90Fe 10) 20Ag 80 nanogranular films prepared by ultra-high vacuum ion ...
Synthesis of Phosphorus Included Multiwalled Carbon Nanotubes by Pyrolysis of Sucrose
(American Chemical Society, 2013)
Multiwalled carbon nanotubes (MWCNT) were synthesized by a pyrolysis route which involves a dehydration step using phosphoric acid. The resultants were found to be mostly containing amorphous carbon with scattered MWCNTs ...
Interface roughness and exchange bias - Coercivity ratio in Pulsed-DC magnetron sputtered NiFe/IrMn/CoFe exchange bias trilayers
(2013)
Ta/Ru/Ta/Ni81Fe19/Ir20Mn 80/Co90Fe10 exchange bias multilayer was grown by using pulsed DC unbalanced magnetron sputtering technique. The deposition pulse frequency of the NiFe seed layer has been varied between 10 - 50 ...
The effects of sintering temperature on phase and pore evolution in porcelain tiles
(Elsevier Sci LTD, 2017)
The phase and pore evolution of porcelain tiling against sintering temperature are investigated in this study. A standard porcelain tile composition was sintered at nine different temperatures between 1150 and 1230 degrees ...
The reaction kinetics of rice husk based cordierite ceramics
(Elsevier Sci LTD, 2008)
In this study, rice husk ash (RHA) was used as a silica source for cordierite production. Two different groups of samples were prepared in order to achieve the synthesis of cordierite. In the first group (HS-0), kaolinite, ...
