Solid State Synthesis of Extra Phase-Pure Li4Ti5O12 Spinel
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
Extra phase-pure Li4Ti5O12 spinel with particle sizes less than 500 nm was synthesized by solid state reaction of mechanochemicaly activated mixture of nano anatase and Li2CO3 for a very short annealing time, 4 h at 800 ...
Analysis and Modeling of Sintering of Sr-hexaferrite Produced by PIM Technology
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
The powder injection moulding (PIM) technology is lately becoming more and more significant due to complex design possibilities and good repeatability. This technology requires optimization of all steps starting with ...
SiC Synthesis Using Natural Mg-Silicates
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
The silicon carbide powders are prepared by carbothermal reduction of domestic mineral resources (white and brown sepiolite), at relatively low temperatures (1200 - 1600 degrees C). Carbothermal reduction process is greatly ...
Electrical properties of mechanically activated zinc oxide
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Microstructural properties of a commercial zinc oxide powder were modified by mechanical activation in a high-energy vibro-mill. The obtained powders were dry pressed and sintered at 1100 degrees C for 2 h. The electrical ...
Synthesis of Barium-zinc-titanate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
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 ...
Optical Properties of CuSe Thin Films - Band Gap Determination
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Copper selenide thin films of three different thicknesses have been prepared by vacuum evaporation method on a glass substrate at room temperature. The optical properties of the films were investigated by UV-VIS-NIR ...
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 ...
Characterisation of Mn0.63Zn0.37Fe2O4 Powders After Intensive Milling and Subsequent Thermal Treatment
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. The goal was to observe intensive milling influences on oxidation and reduction processes ...
Two Step Sintering of ZnTiO3 nanopowder
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Metastable nanopowder ZnTiO3 was pressed into cylindrical compacts at 200 MPa. Compacts were treated by conventional heating with isothermal holding at 931 degrees C for 10 minutes, 25 minutes and 40 minutes. ZnTiO3 compacts ...
