3 Structural, morphological and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Starting nanopowders of TiO2 (anatase 99.7%) and a-Fe2O3 (hematite) were mixed in the weight ratio 60:40 and 40:60. Green samples were sintered in the temperature range 750-1250oC in air. Structural, morphological and ...
Structural analyses of sintered MT and BZT ceramics
(Belgrade : Serbian Society for Microscopy, 2010)
Development of dielectric materials is increasing with a rapid progress in mobile and satellite communications systems, where magnesium titanates find their place owing to good dielectric properties. Recently it has been ...
Characterisation of Mn0.63Zn0.37Fe2O4 powders after intensive milling and subsequent thermal treatment
(Belgrade : Serbian Ceramic Society, 2016)
Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. Powders were characterized with XRD, SEM and particle seizer. Subsequent heating was monitored ...
Modeling, designing and processing of barium titanate stannate
(Belgrade : Serbian Ceramic Society, 2016)
Barium titanate stannate (BTS, BaTi1−xSnxO3) functionally graded materials (FGMs) with an
uniaxial Ti/Sn concentration gradient are very useful for applications in electroceramics, due
to a high dielectric constant in a ...
