DTA/TG analysis of mechanochemicaly activated sodium carbonate
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2021)
Sodium carbonate is a material that is very good sorbent of carbon dioxide from the atmosphere, and it is a reason of it is increasing importance in environmental protection. In order to improve it is sorption characteristics, ...
Hydration of mechanically activated mixtures of Portland cement and fly ash
(University of Chemistry and Technology, Prague, 2007)
Fly ash (FA) can be used in cement mixtures with certain limitations. For experimental purposes, mixtures of Portland cement (PC) and FA were used. The content of FA in the mixtures was either 30% or 50%. The mechanical ...
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 ...
Mehanizam hidratacije mehanički aktiviranih smeša Portland cementa i letećeg pepela / Hydration study of mechanically activated mixtures of Portland cement and fly ash
(Srpsko hemijsko društvo, Beograd, 2007)
Leteći pepeo se može koristiti u cementnim smešama uz određena ograničenja. Problem navedenih smeša ogleda se u nedovoljnoj aktivnosti čestica LP u reakcijama koje su značajne za uspostavljanje mehaničkih karakteristika ...
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 ...
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 ...
