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 of the new lost foam refractory coatings based on talc
(Srpsko hemijsko društvo, Beograd, 2022)
This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a ...
Electrical properties of isothermally sintered cordierite-based ceramics as funcion of sintering and activation time
(Belgrade : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS)Belgrade : Society for Renewable Electrical Power Sources, 2021)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for
sample preparation before the sintering process. Cordierite is a stoichiometric mixture of three different
oxides (2MgO⋅2Al2O3⋅5SiO2). ...
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 ...
Transformations of mechanochemical activated Na2CO3
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2022)
During mechanical activation, energy of treated material is increase to a higher level. This can lead to chemical transformation of the activated material. This is the point where we can talk about mechanochemical ...
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 ...
The influence of mechanical activation of starting components on kinetics of cordierite formation
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2001)
Mechanical activation of simple and complex powder systems is very often used as a method for modification of physico-chemical properties in technologies for obtaining advanced materials. The present work reports on ...
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 ...
Uticaj mehaničke aktivacije na sistem MgO-Al2O3-SiO2 u prisustvu aditiva TeO2 / Influence of mechanical activation on MgO-Al2O3-SiO2 system in the presence of TeO2 additive
(Savez inženjera i tehničara Srbije, Beograd, 2016)
Ova istraživanja posvećena su uticaju mehaničke aktivacije na strukturu kordijeritne smeše 2MgO+2Al2O3+5SiO2. Praćena su i testirana dva paralelna sistema, jedan bez, i drugi u prisustvu 5 masenih % TeO2 kao aditiva. ...
