Influence of one activated component on the sintering process of three phase system
(Belgrade : Materials Research Society of Serbia, 2013)
According to its low temperature thermal expansion coefficient, low dielectric constant, also good mechanical properties, cordierite, 2MgO×2Al2O3×5SiO2, represents a very attractive hightemperature ceramic material. In ...
Influence of MoO3 on cordierite ceramics sintering and crystallization
(Belgrade : Materials Research Society of Serbia, 2013)
The influence of MoO3 on the process of cordierite ceramics preparation, 2MgO-2Al2O3-5SiO2 (MAS) was researched by sintering followed binary systems: MgO/MoO3 (sintered at 850 ºC and 1000 ºC), Al2O3/Bi2O3 and SiO2/Bi2O3 ...
Uticaj mehaničke energije na komponente MgO-Al2O3-SiO2-TiO2 sistema
(Beograd : Savez inženjera i tehničara Srbije, 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 ...
Novel resveratrol delivery systems based on alginate-sucrose and alginate-chitosan microbeads containing liposomes
(Elsevier, 2016)
We reported the design of liposome-loaded Ca-alginate microspheres as a drug delivery system for controlled release of resveratrol. The effect of admixed sucrose and chitosan coating was assessed in terms of physicochemical, ...
Reaction kinetics of mechanically activated cordierite-based ceramics studied via DTA
(Springer, 2016)
Since cordierite, 2MgO·2Al2O3·5SiO2 (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, 5.00 mass% MoO3 was ...
Microstructural and electrical properties of cordierite-based ceramics obtained after two-step sintering technique
(Insternational Institute for the Science of Sintering, 2016)
Cordierite-based ceramic materials are attracting much interest for their various applications in industry, for manufacturing multilayer circuit boards, catalytic converters, filters, thermal insulation, kiln furniture, ...
Sintering of mechanically activated MgO-TiO2 system
(Belgrade : Institute of Technical Sciences of SASA, 2011)
Mixtures of MgO-TiO2 powders were mechanically activated in planetary ball mill for time interval from 0 to 120 minutes. The influence of mechanical activation on phase composition and crystal structure was analyzed by ...
Synthesis and application of silica particles for the removal of heavy metals and pesticide residues from aqueous solutions
(Belgrade : Institute for Multidisciplinary Research, 2019)
In this study, the adsorption behavior of silica adsorbents with different morphology and porosity has been examined in order to evaluate their use for the purification of wastewaters containing toxic environmental chemicals ...
Two step sintering of the ZnTiO3 nanopowder
(Belgrade : Institute for Multidisciplinary Research, University of Belgrade, 2015)
Metastabile nanopowder ZnTiO3 pressed into cylindrical compacts at 200 MPa was submitted to conventional heating with isothermal holding at 931oC for 10 minutes, 25 minutes and 40 minutes. Same compacts were heated with ...
