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 ...
Spectroscopy analysis of activated sodium carbonate
(Belgrade : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS)Belgrade : Society for Renewable Electrical Power Sources, 2023)
Mechanical activation of materials leads to qualitative changes in material structure. These changes can include the accumulation of energy in the form of weakening bonds in the crystal, disruption of the crystal lattice, ...
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 ...
SEM and X-ray analyses of sintered MgO/Bi2O3 binary system
(Bor : University of Belgrade, Technical Faculty in Bor, 2021)
Cordierite, 2MgO⋅2Al2O3⋅5SiO2 is a high-temperature ceramic material. In order to improve its properties, titanium oxide was added to the starting mixture in an amount of 5%. Mechanical activation of samples was performed ...
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 ...
Influence of sintering time on density properties and SEM analysis of cordierite-based ceramics
(Belgrade : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS) Society for Renewable Electrical Power SourcesBelgrade : Society for Renewable Electrical Power Sources, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with
5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction
pressure before the sintering ...
