A phenomenological analysis of sintering kinetics from the viewpoint of activated volume
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2005)
The sintering kinetics of real systems has been viewed as a process of transport of activated volume. Activated volume is a parameter that can be used to describe mass transport during the sintering process. It defines the ...
Electrical properties of ZnO varistors prepared by direct mixing of constituent phases
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Varistor samples containing different amounts of constituent phases were prepared by direct mixing of constituent phases. Detailed electrical characterization was performed to explain the influence of minor phases (spinel ...
Analysis of early-stage sintering mechanisms of mechanically activated BaTiO3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Barium-titanate powder was mechanically activated in a planetary-ball mill for 60 and 120 minutes. Non-isothermal sintering of non-activated and activated powder samples was investigated using a dilatometer in the temperature ...
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 ...
Effect of Binder Molecular Weight on Morphology of TiO2 Films Prepared by Tape Casting and Their Photovoltaic Performance
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Titanium(IV) oxide in the form of anatase has proven to be the best choice for photoanodic material in dye-sensitized solar cells (DSCs). The aim of the work was to study the influence of binder molecular weight on the ...
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 ...
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 ...
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 ...
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 ...
