Application of pyrophyllite in high-temperature treated building materials
(Beograd : Međunarodni Institut za nauku o sinterovanju, 2023)
Phyllosilicate mineral pyrophyllite is predominantly used in the ceramic industry because it exhibits high refractoriness. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures, ...
Fourier-Transform Infrared Spectroscopy Analysis of Mechanochemical Transformation Kinetics of Sodium Carbonate to Bicarbonate
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2022)
During mechanical activation, qualitative changes that can produce various phenomena occur in the material. In this study, anhydrous sodium carbonate was mechanically activated for 2, 7, 14, and 28 minutes in a vibro mill ...
Improving Thermoelectric Properties of p-type (BiSb)2(TeSe)3 Single Crystal by Zr Doping
(Belgrade : Association for ETRAN Society, 2023)
In order to study the effect of Zr doping on the thermoelectric properties of p-type Bi10.17Sb30.72 Zr0.35Te58.28Se0.48 single crystal, аn ingot was prepared by Bridgman method. Cut and cleaved samples from different regions ...
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 ...
Oxide Powder Mixture with Poly-vinyl Alcohol (PVA) and added Polyethylene Glycol (PEG) as Plasticizer
(Belgrade : Association for ETRAN Society, 2023)
Powder mixture consisted of ZnO, Mn2O3 (MnCO3) and Fe2O3 blended powders, was found laminating during compaction. Polyvinyl alcohol (PVA) and a combination of PVA with polyethylene glycol (PEG) added as a plasticizer, were ...
The Bridgman method of (BiAs)2(TeSe)3 bulk single crystal growth by spontaneous nucleation
(Belgrade : Association for ETRAN Society, 2023)
The Bi0.5As1.5Te2.98Se0.02 single crystal in 11 mm × 80 mm size was grown using the Bridgman method. Energy dispersive spectrometry (EDS) analysis was used to determine the chemical composition of the studied samples, as ...
The Crystal Growth of NASICON Phase from the Lithium Germanium Phosphate Glass
(Belgrade : Association for ETRAN Society, 2023)
The crystal growth rate of LiGe2(PO4)3 phase from lithium germanium-phosphate glass was studied. The glass have been homogenized using the previously established
temperature-time conditions, which make it possible to ...
The Analysis of the Nucleation Process of the Lithium Germanium Phosphate Glass
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2022)
The nucleation process of lithium germanium-phosphate glass was studied to determine the temperature range of nucleation and the temperature of the maximum nucleation rate. The differential thermal analysis (DTA), and ...
Thermally induced phase transformation of Mn-LTA and Mn-FAU zeolite to anorthite phases
(Belgrade : Serbian Academy of science and art, 2021)
Data on thermally induced transformations of Mn exchanged zeolites LTA and FAU
topology are presented in this paper. Thermally induced phase transformation of Mn-
exchange zeolites are followed in the range from 700 to ...
