The Influence of Compaction Pressure on the Density and Electrical Properties of Cordierite-based Ceramics
(Science of Sintering, 2015)
Due to its characteristics, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a high-temperature ceramic material of a great scientific interest. Mechanical activation of the starting mixtures containing 5.00 ...
Sintering of Cordierite in the Presence of MoO3 and Crystallization Analysis
(Science of Sintering, 2014)
Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400 degrees C). Because a low temperature process is desirable, it is necessary to find functional ads which can allow ...
Sintering of Fly Ash Based Composites with Zeolite and Bentonite Addition for Application in Construction Materials
(Science of Sintering, 2017)
Due to pozzolanic characteristics, fly ash is commonly used as a cement replacement in construction composites. Addition of natural clays with sorption ability (i.e. zeolite and bentonite) in to the fly ash based construction ...
Synthesis of zirconia colloidal dispersions by forced hydrolysis
(Journal of the Serbian Chemical Society, 2006)
Different zirconia colloidal dispersions (sols) were prepared from zirconyl oxynitrate and zirconyl oxychloride solutions by forced hydrolysis. Vigorously stirred acidic solutions of these salts were refluxed at 102 degrees ...
Laser reflection spot as a pattern in a diamond coating - a microscopic study
(Journal of the Serbian Chemical Society, 2009)
Diamond coatings were deposited by the synchronous and coupled action of a hot filament CVD method and a pulsed CO(2) laser in spectro-absorbing and spectro-non-absorbing diamond precursor atmospheres. The obtained coatings ...
Influence of carbon concentration and rotational temperature on fullerene yield in RF reactor
(Materials Science Forum, 2006)
In this paper, report on fullerene formation in a radio-frequency (RF) thermal plasma reactor has been presented. In order to determine the degree of evaporation of the graphite precursor used, analysis of SEM micrographs ...
Electrophoretic Deposition of Biocomposite Lignin/Hydroxyapatite Coatings on Titanium
(International Journal of Chemical Reactor Engineering, 2009)
In this work, electrophoretic deposition (EPD) was applied to obtain novel hydroxyapatite (HAP)/lignin (Lig) biocomposite coatings on titanium substrate. Nanosized hydroxyapatite powder, prepared by using the modified ...
Synthesis of sillenite-type compounds from zeolite precursors: XRPD and SEM/EDS analyses
(Journal of Optoelectronics and Advanced Materials, 2008)
The paper analyze the possibility of using LTA zeolite as a precursor for obtaining sillenite phase (Bi(12)MO(20), M=Si, Ti, Ge) by hydrothermal synthesis process. The synthesis procedure involves mixing of zeolite (Na-LTA) ...
Surface structures formed on AISI 420 stainless steel by pulsed laser irradiation
(Materials Science Forum, 2005)
The effects of TEA CO2 laser radiation on AISI 420 stainless steel and formed surface structures are studied. The laser energy density of 45.0 J/cm(2) has modified the target surface. Qualitatively, the modifications of ...
Nano-second surface modification of titanium nitride thin film by Nd : YAG and TEA CO2 lasers
(Materials Science Forum, 2006)
In this work we investigated the interaction of ns laser pulses (TEA CO2 and Nd:YAG) with a titanium nitride (TiN) thin film. The TiN thin film of 1 mu m thickness was deposited by PVD method on silicon substrate. Modification ...
