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 ...
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 ...
