The Influence of Synthesis Parameters and Heat Effect on Magnetic Properties of Powder System FexOy - BaTiO3
(Belgrade : Serbian Ceramic Society, 2015)
Powder mixture of 60 mass % of iron (Fe) and 40 mass % of barium titanate (BaTiO3) has been activated in planetary mill for 100, 120, 150, 180, 210 and 240 min in the air. During the activation the iron powder transits ...
Dilatometric Analysis of Mechanically Activated SrTiO3 Powder
(Belgrade : Serbian Ceramic Society, 2013)
Strontium-titanate powder was mechanically activated in a planetary ball mill for 0, 5, 10, 30, 60, 90 and 120 minutes. Non-isothermal sintering of non-activated and activated SrTiO3 powder samples in the temperature ...
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 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 ...
Synthesis of BaFe12O19-BaTiO3 multiferroics by mechanical activation
(Belgrade : Serbian Ceramic Society, 2017)
A mixture of polycrystalline powders of Fe (70 % wt.) and BaTiO3 (30 % wt.) was ball-milled in a planetary mill under air atmosphere, for different time intervals: 60, 120, 180, 240, 300 and 360 min. During the mechanical ...
Compaction pressure's influence on density and electrical properties of sintered cordierite-based ceramics
(Belgrade : Materials Research Society of Serbia; Institute of Technical Sciences of SASA; Vinča Institute of Nuclear Sciences, University of Belgrade, 2012)
Mechanical activation is widely used for sample preparation before the sintering process. However, the influence of pressure, which is used for compaction, has not been completely investigated. Cordierite, 2MgO_2Al2O3_5SiO2, ...
