Youngs Modulus Evaluation and Thermal Shock Behavior of a Porous SiC/cordierite Composite Material
(Science of Sintering, 2015)
Porous SiC/Cordierite Composite Material with graphite content (10%) was synthesized. Evaluation of Young modulus of elasticity and thermal shock behavior of these samples was presented. Thermal shock behavior was monitored ...
Kinetics of the alpha-beta Phase Transformation in Seeded Si3N4 Ceramics
(Science of Sintering, 2008)
The alpha-beta phase transformation in Si3N4 was studied for seeded samples using all Y2O3-Al2O3 mixture as a sintering aid. The concentration of beta-seeds varied from 0 to 5 wt.%. The results showed that alpha-beta phase ...
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 ...
Advantages of Combined Sintering Compared to Conventional Sintering of Mechanically Activated Magnesium Titanate
(Science of Sintering, 2014)
In this article, the advantages of combined sintering in comparison with the conventional one, of mechanically activated magnesium titanate ceramic were investigated. The stoichiometric mixtures of MgO and TiO2 were ...
Properties of Zig-Zag Nickel Nanostructures Obtained by GLAD Technique
(Science of Sintering, 2016)
Zig-zag structure of the nickel thin film has been obtained using Glancing Angle Deposition (GLAD) technique. Glass substrate was positioned 75 degrees with respect to the substrate normal. The obtained nickel thin film ...
Synthesis of Highly Porous Al2O3-YAG Composite Ceramics
(Science of Sintering, 2016)
Al2O3-YAG composite was obtained by sintering of porous Al2O3 preforms infiltrated with water solution of aluminium nitrate nonahydrate, Al(NO3)(3)center dot 9H(2)O and yttrium nitrate hexahydrate, Y(NO3)(3)center dot ...
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 ...
Thermal Shock Properties of Glass-ceramics Synthesized From a Glass Frit
(Science of Sintering, 2017)
In this study, the behavior of glass-ceramics synthesized from a glass frit of FFW (Final Flotation Waste) originated from the RTB Bor Company was investigated. Thermal shock resistance was monitored in order to assess the ...
Argon Irradiation Effects on the Structural and Optical Properties of Reactively Sputtered CrN Films
(Science of Sintering, 2015)
The present study deals with CrN films irradiated at room temperature (RT) with 200 keV Ar+ ions. The CrN layers were deposited by d.c. reactive sputtering on Si (100) wafers, at nitrogen partial pressure of 5x10(-4) mbar, ...
Synthesis of Anatase Nanopowders by Sol-gel Method and Influence of Temperatures of Calcination to Their Photocatalitic Properties
(Science of Sintering, 2015)
The titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor, varying the temperature of calcination (from 500 to 550 degrees C with the step of 10 degrees C). XRPD ...
