Gözenekli silisyum dioksit peletlerinin 2,8 V potansiyel farkı uygulanarak CaCl2 tuzu ve CaCl2-NaCl tuz çözeltisi içerisinde elektrodeoksidasyon yöntemiyle indirgenmesi incelenmiştir. Çalışma, katotta kullanılan iletken malzemelerin, sıcaklığın ve tane boyutunun indirgenmeye olan etkilerinin araştırılmasını içermektedir. Başlangıçta kullanılan malzemelerin ve elektroliz sonucunda elde edilen ürünlerin yapısı ve morfolojisi X-ışınları kırınımı analizi ve taramalı elektron mikroskobu ile belirlenmiştir. Nikel ve paslanmaz çelik katotta iletken malzemeler olarak kullanılmış ve katotta oluşan silisyumun katot iletken malzemesi olarak kullanılan metallerle reaksiyona girdiği görülmüştür. X-ışınları kırınımı analizi ile silisyumun, katot iletken malzemesi olarak kullanılan nikelle nikel-silis bileşikleri oluşturduğu, paslanmaz çelik içindeki demirle de demir-silis bileşikleri oluşturduğu belirlenmiştir. Oluşan nikel-silis bileşiklerinin, miktar olarak, demir-silis bileşiklerinden daha fazla olduğu görülmüştür. Sonuçlar, akım zaman grafikleri, kompozisyonlar ve mikroyapılar incelenerek yorumlanmıştır.

Reduction of silicon dioxide by electrochemical deoxidation Ergül, Emre; Karakaya, İshak; Department of Metallurgical and Materials Engineering (2010) Electrochemical reductions of porous SiO2 pellets and bulk SiO2 plate were investigated in molten CaCl2 and/or CaCl2-NaCl salt mixture. The study focused on effects of temperature, particle size of the starting material, electrolyte composition and cathode design on the reduction rate. The behavior of the cathode contacting materials was also examined. Moreover, cyclic voltammetry study was conducted to investigate the mechanism of the electrochemical reaction. Mainly, XRD analysis and SEM examinations were...
Electrochemical decomposition of SiO2 pellets to form silicon in molten salts Ergul, Emre; Karakaya, İshak; Erdogan, Metehan (Elsevier BV, 2011-01-21) Direct electrochemical reduction of porous SiO2 pellets in molten CaCl2 salt and CaCl2-NaCl salt mixture was investigated by applying 2.8 V potential. The study focused on the effects of temperature, particle size of SiO2 powder starting material and the behavior of cathode contacting materials during electrochemical reduction process. The starting materials and the electrolysis products were characterized by X-ray diffraction analysis and scanning electron microscopy mainly. The studies showed that smaller...
Characterization of magnetite thin films produced by sol-gel processing Eken, Ali Erdem; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2008) Magnetite (Fe3O4) thin films were prepared by a sol-gel process in which, a solution of iron (III) nitrate dissolved in ethylene glycol was applied on glass substrates by spin coating. Xerogel films were obtained by drying the coated films at 110 °C. The films were sintered between 300 °C and 450 °C in order to observe the phases existing in the films at different temperatures. Coating solution showed Newtonian behaviour and viscosity was found as 0.0215 Pa.s. DTA analysis showed that, sintering temperature...
AN EXPERIMENTAL INVESTIGATION OF POSSIBLE PRODUCTION MECHANISMS OF HYDRATE FORMATION Engüçlü, Hasan Hüseyin; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2021-9-10) In this study, temperature, pressure and mole values of methane hydrate formation and dissociation are analyzed using different production methods under laboratory conditions. During the experiments, a cylindrical high-pressure hydrate cell in a constant temperature room was used. In order to provide the real field conditions of the hydrate reservoirs, methane gas was injected at high pressure into the cell filled with sand and water at low temperatures, and the hydrate reservoir was formed in a 21.2 *liter...
Homogeneous catalysts for the hydrolysis of Sodium Borohydride : synthesis, characterization and catalytic use Masjedi, Mehdi; Özkar, Saim; Department of Chemistry (2010) Recent study has shown that ruthenium(III) acetylacetonate acts as a homogeneous catalyst in the hydrolysis of sodium borohydride. When two equivalents of trimethylphosphite per ruthenium is added to the reaction solution containing sodium borohydride and ruthenium(III) acetylacetonate in the mixture of water and tetrahydrofuran, the rate of hydrogen generation is practically stopped (or reduced to the level of self hydrolysis). However, the catalytic hydrogen evolution of sodium borohydride restarts at an ...
