Density of the ZnTiO3 nanopowder as a loose powder and as a compact obtained by different methods
(Belgrade : Serbian Ceramic Society, 2013)
Nanopowder density, as well as compact density, is due to powder particle size, different in their values, compared to micron powders. Also, the technique used for density determination induces large mutual value discrepancies. ...
ZnTiO3 ceramic nanopowder microstructure changes during compaction
(Belgrade : International Institute for the Science of Sintering, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterized. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
Structural analysis of Zn2TiO4 doped with MgO
(Springer, 2009)
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
Sinterovanje i svojstva sinterovanog ZnTiO3
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2011)
Ultrafini prah cink-metatitanata veličine čestica 40 do 80 nm podvrgnut je prilikom sintetskog dela tretmana uticajima pritiska i temperature korišćenjem procesa presovanja i reakcionog sinterovanja. S obzirom na nestabilnost ...
Two step sintering of ZnTiO3 nanopowder
(Belgrade : International Institute for the Science of Sintering, 2017)
Metastable nanopowder ZnTiO3 was pressed into cylindrical compacts at 200 MPa. Compacts were treated by conventional heating with isothermal holding at 931°C for 10 minutes, 25 minutes and 40 minutes. ZnTiO3 compacts were ...
Sinterovanje i svojstva sinterovanog ZnTiO3
(2011)
PhD defence presentation. The thesis "Sintering and Properties of Sintered ZnTiO3" was defended at the University of Belgrade, Faculty of Physical Chemistry, in 2011.
Influence of mechanical activation on synthesis of zinc metatitanate
(Belgrade : International Institute for the Science of Sintering, 2005)
Investigations of a ZnO-TiO2 binary oxide mixture during mechanical treatment were mainly focused on obtaining orthotitanate Zn2TiO4 with a spinel structure. Due to the specific way of energy transfer during mechanical ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
(Elsevier, 2009)
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...
Microstructure changes caused by thermal etching of sintered ZnTiO3
(2014)
Polishing and thermal etching was performed on ZnTiO3sintered ceramic. Two set of specimens were recorded, on higher 1200oC/1100oC sintered/etched, and lower 900oC/800oC sintered/etched. Phase composition, crystallite sizes ...
