Sol-gel Synthesis of Anatase Nanopowders for Efficient Photocatalytic Degradation of Herbicide Clomazone in Aqueous Media
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
TiO2 nanopowders were produced by sol-gel technique using TiCl4 as a starting material. For the preparation of crystalline anatase with developed surface area, this aqueous solution has been mixed with 0.05 M or 0.07 M ...
Formation of Porous Wollastonite-based Ceramics after Sintering With Yeast as the Pore-forming Agent
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
In this paper, synthesis of porous wollastonite-based ceramics was reported. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min of ultrasound treatment, ...
Electrospun Alumina Fibers Doped With Ferric and Magnesium Oxides
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
It is well known that alumina possesses good mechanical and chemical properties. Nanofibers having alpha - alumina structure was used as reinforcement for metal, polymer and ceramic matrix composites. In this study, three ...
Structure and photocatalytic properties of sintered TiO2 nanotube arrays
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by electrochemical oxidation of titanium foil in an acid electrolyte. In order to alter the crystallinity and the morphology of films the ...
Determination of Degradation Level during Cavitation Erosion of Zircon Based Ceramic
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Mechanical shock of zircon based ceramic induced by cavitation erosion testing was investigated in this study. Several parameters were followed in order to determine level of material degradation during the cavitation ...
Magnetic properties of ND Rich Melt-Spun ND-FE-B alloy
(International Institute for the Science of Sintering, Beograd, 2005)
As a part of these experimental investigations of melt-spun Nd-Fe-B alloy with Nd rich content in relation to Nd2Fe14B prepared by rapid quenching process for optimally selected cooling rate and heat treatment, the influence ...
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 ...
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 ...
