Improvement of the mechanical properties of spark plasma sintered hap bioceramics by decreasing the grain size and by adding multi-walled carbon nanotubes
(International Institute for the Science of Sintering, Beograd, 2013)
Composites based on HAP and oxidized multi-walled carbon nanotubes (o-MWCNT) and monophase HAP materials were processed by spark plasma sintering. Starting from stoichiometric nano-sized HAP powder, monophase bioceramics ...
Mechanical properties of biomorphic silicon carbide ceramics
(International Institute for the Science of Sintering, Beograd, 2011)
Biomorphous β-SiC ceramics were produced from linden wood by impregnation with tetraethyl orthosilicate (TEOS), followed pyrolysis and high temperature treatment at 1580°C. Six specimen groups included charcoal and five ...
Characterization of dispersion strengthened copper with 3wt%Al2O3 by mechanical alloying
(International Institute for the Science of Sintering, Beograd, 2004)
The copper matrix has been dispersion strengthened with 3wt.%Al2O3 by mechanical alloying. Commercial alumina powder with an average particle size of 0.75mm was used for alloying. The mechanical alloying process was performed ...
Mechanical properties correlation to processing parameters for advanced alumina based refractories
(International Institute for the Science of Sintering, Beograd, 2012)
Alumina based refractories are usually used in metallurgical furnaces and their thermal shock resistance is of great importance. In order to improve thermal shock resistance and mechanical properties of alumina based ...
SiC synthesis using natural Mg-silicates
(International Institute for the Science of Sintering, Beograd, 2012)
The silicon carbide powders are prepared by carbothermal reduction of domestic mineral resources (white and brown sepiolite), at relatively low temperatures (1200 - 1600oC). Carbothermal reduction process is greatly ...
Influence of sintering temperature on raw and beneficiated clay 'Klokoti'
(International Institute for the Science of Sintering, Beograd, 2012)
The raw clay 'Klokoti' from middle Bosnia was beneficiated by method of wet separation which results in removing fraction over 20 μm. The raw clay was characterized by chemical composition, grain size distribution and ...
Thermal Shock Properties of Glass-ceramics Synthesized From a Glass Frit
(Međunarodni Institut za nauku o sinterovanju, Beograd, 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 ...
The use of image analysis for determination of surface deterioration level of improved alumina based materials subjected to cavitation
(International Institute for the Science of Sintering, Beograd, 2013)
Alumina based specimens having different content of alumina based fibers were investigated for possible application as cavitation resistant material. Cavitation damages of the alumina based specimens were tested by the ...
Structural, Chemical and Magnetic Properties of Nickel Vertical Posts Obtained by Glancing Angle Deposition Technique
(Science of Sintering, 2017)
In this work, Glancing Angle Deposition technique was used for obtaining nanostructured nickel thin film with vertical posts on glass substrate which was positioned 75 degrees with respect to the substrate normal and rotated ...
Alumina Particles Doped With Ferric as Efficient Adsorbent for Removal of Reactive Orange 16 from Aqueous Solutions
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
Ferric oxide doped alumina particles were prepared via the sol-gel method and their performance as Reactive Orange 16 adsorbent was evaluated. The concentrations of the Reactive Orange 16 were monitored using a UV-Vis ...
