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 ...
Kinetics of the Bray-Liebhafsky oscillatory reaction perturbed by polymer supported cobalt catalyst
(International Institute for the Science of Sintering, Beograd, 2011)
The Bray-Liebhafsky (BL) oscillatory reaction generated in the batch reactor at 62- 68 oC was perturbed by cobalt(II)-nitrate, supported on the macroreticular copolymer of poly-4-vinylpyridine with divinylbenzene (Co-PVPDVB). ...
The Characterization of Sintered SmCo5 Magnets
(Association for ETRAN Society, 1999)
During the investigation and design of laboratory model of a Sintered SmCo5 magnet, a group of methods for characterizing sintered and heat treated magnets was defined. The direct dependence of the magnetic properties of ...
Mechanical Properties of Biomass-derived Silica Nanoparticles Reinforced PMMA Composite Material
(Science of Sintering, 2022)
Rice husk was used to produce silica particles, which were then used to reinforce the polymer matrix. The synthesized SiO2 particles were characterized using X-ray diffraction, Fourier transforms infrared spectroscopy ...
Fourier-transform infrared spectroscopy analysis of mechanochemical transformation kinetics of sodium carbonate to bicarbonate
(ETRAN Society, 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 ...
Deterioration Characterization during Thermal Shock Testing
(International Institute for the Science of Sintering (IISS), 2023)
Thermal shock stability plays a great role in the selection of optimal refractory material. Different methods of characterization were developed for this purpose, including the implementation of nondestructive testing. ...
Structure and Properties of Nanocrystalline Tetragonal BaTiO3 Prepared by Combustion Solid State Synthesis
(International Institute for the Science of Sintering, 2020)
Barium titanate (BaTiO3) attracts high scientific and technological attention due to good dielectric and electromechanical properties. Although BaTiO3 is one of the most frequently investigated ferroelectric materials, the ...
Characterization of cobalt ferrite nanoparticles obtained by various synthesis methods and comparison with the Raman spectra of other ferrites and some cubic oxide spinels / Kарактеризација наночестица кобалт ферита добијених различитим методама синтезе и поређење са Рамановим спектрима других ферита и неких кубичних оксидних спинела
(Association for ETRAN Society, 2023)
ingle phase cobalt ferrite (CoFe2O4) with nanoparticles of similar sizes (15.7-19 nm) was obtained by different synthesis methods: coprecipitation, ultrasonically assisted coprecipitation, coprecipitation followed by ...
The influence of strontium content and sintering temperature on monazite stability
(Association for ETRAN Society, 2023)
This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple ...
Effect of Sintering Temperature and Calcium amount on Compressive Strength of Brushite-Metakaolin Polymer Materials
(Association for ETRAN Society, 2022)
The effect of Ca2+ amount and sintering temperature on mechanical properties of geopolymer-brushite (GPB) binders was investigated. Brushite and raw abandoned kaolinite clay thermally transformed into metakaolin were used ...
