Optimization of the Corrosion Behavior of Mullite Refractories Against Alkali Vapor Via Zrsio4 Addition to the Binder Phase
(University Chemistry & Technology, Prague, 2009)
Effect of ZrSiO4 addition to the binder matrix of the reaction sintered mullite refractories on the alkali corrosion (Na2CO3, at 1370 degrees C) behaviour was investigated. Important improvements on the corrosion behaviour ...
Characterization of diopside-based glass-ceramic porcelain tile glazes containing borax solid wastes
(Korean Assoc Crystal Growth, Inc, 2011)
In recent years glass-ceramic systems became industrially important for their high softening point, good coating capability for relevant substrates and high chemical and abrasion resistance. The ZrO2-CaO-MgO-SiO2 (ZrCMS) ...
The effects of re-firing process under oxidizing atmosphere and temperatures on the properties of strontium aluminate phosphors
(Pergamon-Elsevier Science LTD, 2013)
Inorganic phosphorescent pigments have a very wide application, consisting of ceramic decoration and glazes. Therefore, in the present study 3 different commercially available strontium aluminate phosphors (coded Phosphor ...
Catalytic Applications of Large Pore Sulfonic Acid-Functionalized SBA-15 Mesoporous Silica for Esterification
(De Gruyter Poland Sp Zoo, 2018)
We report the preparation of pore expanded and sulfonic acid functionalized mesoporous silica catalysts by using different kinds of swelling agents such as 1,3,5-trimethyl benzene (TMB), n-decane (D), n-tridecane (TD), and ...
High-surface-area SBA-15-SO3H with enhanced catalytic activity by the addition of poly(ethylene glycol)
(Springer, 2013)
The influence of poly(ethylene glycol) (PEG) and synthesis temperature in the synthesis of SBA-15-SO3H was investigated to evaluate the catalytic activity in the esterification of propionic acid with methanol. The catalysts ...
Effect of calcination temperature on the structural and magnetic properties of Ni/SBA-15 nanocomposite
(Springer, 2015)
The effect of calcination temperature on the structural and magnetic properties of Ni/SBA-15 nanocomposite prepared by reductant-impregnation method was studied using SBA-15 mesoporous silica as support. The structure, ...
Bifunctional Fe-SBA-15-SO3H Mesoporous Catalysts with Different Si/Fe Molar Ratios: Synthesis, Characterization and Catalytic Activity
(Wiley-V C H Verlag GMBH, 2013)
Bifunctional Fe-SBA-15-SO3H mesoporous materials with different Si/Fe molar ratios (3, 5, and 7) have been synthesized via a simple direct hydrothermal method and characterized by XRD, N-2-adsorption/desorption, TG/DTG and ...
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 ...
Synthesis, characterization and catalytic behavior of functionalized mesoporous SBA-15 with various organo-silanes
(Academic Press Inc Elsevier Science, 2012)
Mesoporous silica SBA-15 has been synthesized and functionalized by one-step synthesis method to widen their various application possibilities. In this study, phenyltrimethoxysilane (PTMS), 3-mercapto-propyltrimethoxysilane ...
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 ...
