Effect of Mechanical Activation on the Densification Behavior of MgAl2O4 Spinel
(The Ceramic Society of Japan, 2019)
Magnesium aluminate and other alumina-based spinels attract attention due to their high hardness, high mechanical strength, and low dielectric constant. MgAl2O4 was produced by solid-state reaction between MgO and a-Al2O3 ...
Uticaj mehaničke aktivacije na sintezu cink-metatitanata
(Čačak : University of Kragujevac, Faculty of Technical Sciences, Čačak, 2005)
U ovom radu analiziran je uticaj mehaničke aktivacije na sintezu cink-meta titanata (ZnTiO3). Polazeći od toga da mehanička aktivacija utiče na strukturu praha, menjajući je za naknadnu sintezu procesom sinterovanja, mi ...
The influence of mechanical activation on structural evolution of nanocrystalline SrTiO3 powders
Structural changes caused by mechanical activation of SrTiO3 powders were investigated using a variety of methods. Average crystallite size continuously decreased with increased activation time to around 20 nm after 120 ...
