Influence of prolonged sintering time on density and electrical properties of isothermally sintered cordierite-based ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
Mehanička aktivacija je brza i jeftina procedura koja se obično koristi za pripremanje uzoraka pre procesa sinterovanja. Kordijerit, stehiometrijska mešavina tri različita oksida (2MgO⋅2Al2O3⋅5SiO2) je veoma atraktivan, i ...
New directions of the application of micronizing mineral raw materials
(Bor : University of Belgrade, Technical Faculty in Bor, 2017)
The paper aims to show the wide application of micronized products that arise after micronization milling. Fine-tinted-micronized materials such as alumosilicates, lycones, non-metallic mineral raw materials, thanks to ...
The influence of mechanical activation of talc-filler on the quality of the refractory coatings
(Bor : University of Belgrade, Technical Faculty in Bor, 2017)
For development of the refractory coatings with controlled rheologic properties, for application in new Lost Foam casting process, the influence of the mechanical activation on the talc-based filler’s properties change was ...
Effect of micronized grinding on the quality of the fillers based on cordierite, mullite and zircon
(XVII Balkan Mineral Processing Congress, 2017)
This study presents the results of an investigation of high temperature materials – refractory filler based on cordierite, mullite and zircon for the synthesis of new refractory pattern coating and application in foundry. ...
To what extent do soft mechanical activation and process parameters increase the efficiency of different zeolite/phosphate rock fertilizer mixtures?
(Savez hemijskih inženjera, Beograd, 2017)
In order to obtain effective mineral fertilizer, different mixtures of phosphate rock (PR) with natural clinoptilolite (Cp) and NH4+ saturated clinoptilolite (NH4-Cp) were subjected to soft mechanical activation. Mean ...
Synthesis and sintering of high-temperature composites based on mechanically activated fly ash
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Količina letećeg pepela koji se proizvodi i koja će biti proizvedena u godinama koje dolaze zahteva razvoj novih metoda recikliranja u kojima će biti upotrebljene značajne količine ovog otpadnog materijala. Mogućnost ...
Uticaj mehaničke energije na komponente MgO-Al2O3-SiO2-TiO2 sistema / Influence of mechanical activation on the constituents of the MgO-Al2O3-SiO2-TiO2 system
(Savez inženjera i tehničara Srbije, Beograd, 2012)
U ovom radu je ispitivan uticaj mehaničke energije na strukturu i promene u mikrostrukturi sistema MgO-Al2O3-SiO2-TiO2. Utvrđeno je da mehanička energija pospešuje homogenizaciju polaznih komponenti, utiče na veličinu i ...
Electrical properties of mechanochemically activated cordierite ceramics
(Springer, New York, 2012)
Three-component oxide mixtures were prepared containing MgO, Al (2) O (3) and SiO (2) in a 2 : 2 : 5 ratio with addition of 10% Bi (2) O (3). The mixtures were mechanically activated in a range from 5 to 240 min in a mill ...
