Sintering of mechanically activated Zno-TiO 2 powders
(Springer, 2008)
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...
Influence of platinization of mechanically activated nuclear grade graphite powders on the hydrogen adsorption process
(Belgrade : Vinča Institute of Nuclear Sciences, University of BelgradeBelgrade : Hydrogen Economy Initiative Serbia, 2018)
Non-activated powder of nuclear grade graphite and powders of nuclear grade graphite that were milled for 10, 20 and 30 minutes are doped with 0.03% of platinum. XRD analysis of injtial and activated graphite powders was ...
Structural characterization of mechanically activated MgO-TiO2 system
(Belgrade : Materials Research Society of Serbia, 2011)
Mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for time interval from 0 to 120 minutes. On thus obtained powders, structural investigations have been performed. N2 adsorption method was ...
Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of γ to α phase transformation mechanism
(Elsevier, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
Phase Formation at the Sintering of Sa, Zn, Ti Oxides
(Kiev, 2009)
Complex compounds with oxide phases of Ba, 2n, and 11 are widely used in instrument engineering. It is also important to find such production routes for ceramics, which provide their stable structure and properties. Phase ...
Structural investigation of mechanically activated ZnO powder
(Elsevier, 2015)
Abstract Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ...
Influence of synthesis parameters and thermal treatment on functional properties of Fe3O4-BaTiO3 multiferroics obtained by mechanical activation
(Belgrade : Serbian Ceramic Society, 2017)
Mechanical activation of a mixture of polycrystalline powders Fe3O4 (50% wt.) and BaTiO3 (50% wt.) was performed in a planetary ball-mill, with different milling times (3 h, 6 h and 12 h). Average crystallite size determined ...
Structural and electrical properties of ferroelectric poly(vinylidene fluoride) and mechanically activated ZnO nanoparticle composite films
(IOP Publishing, 2018)
The influence of the mechanical activation of ZnO nanoparticle fillers on the structural and electrical properties of the matrix of poly(vinylidenefluoride)-ZnO (PVDF-ZnO) films was investigated. Transmission electron ...
Processing and properties of dense cordierite ceramics obtained through solid-state reaction and pressure-less sintering
(Taylor and Francis, 2019)
Sintering of pure cordierite 2MgO:2Al2O3:5SiO2, and cordierite with the addition of 5 mass % TeO2 was studied. Green bodies were prepared from powder mixtures mechanically activated in a high-energy planetary mill, shaped ...
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 ...
