SERAMİK SAĞLIK GEREÇLERİ BÜNYELERİNDE CAMSI FAZ KOMPOZİSYONUNUN PİŞİRİM SICAKLIKLARINA ETKİSİ
(2013)
Bu çalışmada seramik sağlık gereçleri bünyelerinde, kimyasal kompozisyonla birlikte camsı faz viskozitesinin
değişimi incelenmiştir. Ayrıca, bu değişimin sinterleme sıcaklıkları üzerine etkisi araştırılmıştır. Seramik
bünyedeki, ...
Wear behavior of solid SiAlON milling tools during high speed milling of Inconel 718
(Elsevier Science Sa, 2017)
Machining of Inconel 718 is a challenging process because of high hot strength and hardness, high reactivity with the tool materials and low thermal conductivity of Inconel 718 alloy. Although SiAION ceramics in the form ...
Characterization of Ni-W solid solution alloy powders and sintered compacts synthesized via mechanically activated hydrogen reduction of NiO-WO3 mixtures
(2013)
Blended nickel oxide - tungsten oxide powders corresponding to the compositions of 70 wt% nickel - 30 wt% tungsten were mechanically alloyed (MA'd) for different durations such as 0 h, 6 h, 12 h and 24 h and reduced/alloyed ...
Characterization of underclays from Agaçli-Kemerburgaz region of Istanbul/Turkey and their evaluation for porcelain tile production
(2011)
Agacli-Kemerburgaz area, NW of Istanbul, is one of the most important underclay deposits of Turkey. This area is composed of Paleozoic sedimentary sequence, Upper Cretaceous volcanic rocks, Neogene sediments and Quaternary ...
Excited state dynamics of nanocrystalline VO2 with white light continuum time resolved spectroscopy
(Elsevier Science BV, 2014)
In an attempt to use ultrafast pump probe spectroscopy technique with white light continuum to reveal wavelength dependent dynamics of VO2, bandgap needs to be opened. Therefore, nanostructured amorphous and crystalline ...
Use of rhyolite as flux in porcelain tile production
(Techna Srl, 2009)
The use of rhyolite from a local source as an alternative fluxing agent in a commercial porcelain stoneware formulation was investigated. The experimental work was achieved in two parts: in the first part, standard tests ...
Incorporation of the transition metals (Cr and Fe) into beta-SiAlON crystal structure
(Elsevier Sci LTD, 2011)
Outstanding properties for SiAlON ceramics can be obtained by tailoring the microstructure through alpha-SiAlON and beta-SiAlON phase content as well as a type of secondary phases. It is so far well known that while some ...
Production technology and provenance study of brittle wares belonging to the late roman period from Harabebezikan/Turkey
(Elsevier Sci LTD, 2017)
This study represents analyses of Brittle Ware sherds dated back to the Late Roman period found in the Harabebezikan Mound (Banhurfa/Turkey). Wavelength dispersive X-ray fluorescence (WDXRF) was performed for chemical ...
Young's modulus measurements of magnesia-spinel composites using load-deflection curves, sonic modulus, strain gauges and Rayleigh waves
(Elsevier Sci LTD, 2003)
The extent of interlinking of the microcracking and a decrease in strength and modulus values were determined to be a function of both spinel particle size and volume fraction to allow calculation of thermal shock parameter, ...
The mechanism for the colour change of iron chromium black pigments in glazes through transmission electron microscopy techniques
(Elsevier Sci LTD, 2011)
Black iron chromium (Fe-Cr) bearing oxide pigments are generally utilised as effective colourants in a wide variety of applications. However, in the case of their use within ZnO-containing glazes, they yield an undesirable ...
