Kinetics of specific surface area change using the Boltzmann model
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
Sinterovanjem sistema 2MgO·2Al2O3·5SiO2, dobija se kordijerit, koji zbog svojih svojstava predstavlja izuzetno atraktivan keramički materijal. U cilju ispitivanja mogućnosti sniženja temperature formiranja kordijerita tokom ...
Rujevac Sb-Pb-Zn-As polymetallic deposit, Boranja orefield, Western Serbia: native arsenic and arsenic mineralization
(Springer Wien, Wien, 2014)
Rujevac is a low-temperature hydrothermal polymetallic Sb-Pb-Zn-As vein-type ore deposit, hosted within a volcanogenic-sedimentary zone situated in the Rujevac-Crvene Stene-Brezovica Diabase-Chert Formation (DCF) of the ...
Functionality of chitosan-halloysite nanocomposite films for sustained delivery of antibiotics: The effect of chitosan molar mass
(Wiley, Hoboken, 2020)
This study was designed to investigate functionality of tetracycline-loaded chitosan-halloysite nanocomposite films, with focus on evaluating the influence of chitosan molar mass on films applicability for sustained local ...
The Influence of Compaction Pressure on the Density and Electrical Properties of Cordierite-based Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
Due to its characteristics, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a high-temperature ceramic material of a great scientific interest. Mechanical activation of the starting mixtures containing 5.00 ...
Influence of natural zeolitic tuff and organozeolites surface charge on sorption of ionizable fumonisin B-1
(Elsevier, Amsterdam, 2010)
Natural Zeolitic tuff was modified with 2, 5 and 10 mmol M+/100 g of octadecyldimethylbenzyl ammonium (ODMBA) ions and the products were denoted as OZ-2, OZ-5 and OZ-10. The starting material and organozeolites were ...
Thermal Decomposition and Kinetics of Pentlandite-Bearing Ore Oxidation in the Air Atmosphere
(MDPI, Basel, 2021)
The roasting of sulfide ores and concentrates is one of the most important steps in pyrometallurgical metal production from primary raw materials, due to the necessity of excess sulfur removal, present in the virgin material. ...
Cavitation Properties of Rendering Mortars with Micro Silica Addition
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
Micro-silica is a highly efficient mineral additive whose role is reflected in improvements of microstructure packing, strength and durability of non-shaped composite building materials such as concrete and mortar. A ...
Thermodynamic Aspect of Sodium Carbonate Mechanical Transformations under Different Environment
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2020)
During mechanical activation, the energy of treated material is raised to a higher level that can lead to the chemical transformation of the activated material. This is the point that should be considered as a phenomenon ...
Natural and Modified Zeolite-Alginate Composites. Application for Removal of Heavy Metal Cations from Contaminated Water Solutions
(MDPI, Basel, 2018)
In present paper, the influence of the initial pH and concentration of Pb2+ on its adsorption by the natural (NZA) and Fe(III)-modified zeolite-alginate beads (FeA) was studied. Results showed that modification of the ...
Reaction kinetics of mechanically activated cordierite-based ceramics studied via DTA
(Springer, Dordrecht, 2016)
Since cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2) (MAS), is a very useful high-temperature ceramic material, it is important to decrease its sintering temperature. In order to accelerate the process of sintering, ...
