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 ...
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 ...
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 ...
Influence of Er3+/Yb3+ Concentration Ratio on the Down-conversion and Up-conversion Luminescence and Lifetime in GdVO4:Er3+/Yb3+ Microcrystals
(Science of Sintering, 2015)
In this paper, we studied the effects of Er3+/Yb3+ concentration ratio on structural, morphological and luminescence properties of GdVO4:Er3+/Yb3+ green phosphors prepared by a high-temperature solid state method. The ...
Natural Diatomite (Rudovci, Serbia) as Adsorbent for Removal Cs from Radioactive Waste Liquids
(Science of Sintering, 2015)
The removal of Cs (I) ions from aqueous solution was studied using natural diatomite as adsorption materials originated from Rudovci, Serbia. The microstructure of natural diatomite has been characterized by X-ray diffraction ...
