The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Sintering of different hydroxyapatite nanopowders
Poster presented at the Workshop: Processing of Nanostructured Ceramics, Polymers, and Composites, Faculty of Technology and Metallurgy, University of Belgrade, November 29–30, 2010
Pseudobrookite TiFe2O5 nanostructured thick films
(Belgrade : Institute of Technical Sciences of SASA, 2015)
TiO2 (anatase) and Fe2O3 (hematite) nanopowders were mixed in the weight ratio 1:1.5 and 1:2 and homogenized in a planetary ball mill for an hour. After that pastes were prepared of the two powder mixtures, organic vehicle ...
