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 ...
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 ...
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 ...
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 ...
Pore Geometry of Ceramic Device: the Key Factor of Drug Release Kinetics
(Science of Sintering, 2013)
Release kinetics of tigecycline, a potential antibiotic in treatment of osteomyelitis, from calcium hydroxyapatite (CHA), as one of the most important ceramic materials in bone tissue engineering, was investigated in this ...
Structure and Magnetic Investigations of Ca1+xYxMnO3 (x=0, 0.1, 0.2, 0.3) and Mn4+/Mn3+ Relation Aanalysis
(Science of Sintering, 2010)
Structure and magnetic features of nanostructured materials with general formula Ca1-xYxMnO3 (x = 0; 0.1; 0.2; 0.3) were investigated. Goldschmidt tolerance factor, G, and global instability index, GII were calculated for ...
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 ...
Synthesis and Characterization of Cu-ZrB2 Alloy Produced by PM Techniques
(Science of Sintering, 2014)
The copper alloy with 7vol.% ZrB2 examined in this study was consolidated via powder metallurgy processing (PM) by combining mechanical alloying and hot pressing process. Structural changes, morphological properties and ...
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 ...
Yttrium Orthoferrite Powder Obtained by the Mechanochemical Synthesis
(Science of Sintering, 2017)
Yttrium orthoferrite (YFeO3) powder was prepared by a mechanochemical synthesis from a mixture of Y2O3 and alpha-Fe2O3 powders in a planetary ball mill for 2.5 h. The obtained YFeO3 powder sample was characterized by X-ray ...
