Influence of Mechanical Activation on Electrical Properties of Ceramic Materials in VHF Band
(Belgrade : ETRANBelgrade : Academic Mind, 2019)
Mechanical activation is commonly used as a pre-sintering process in order to enhance the reactivity of materials, reduce the particle size, increase diffusion rates, accelerate the reaction, and lower the sintering ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Societa ceramica italianaPolitecnico di Torino, 2019)
Magnesium aluminate, MgAl2O4, and other alumina-based spinels are refractory ceramics with high hardness and resistance to chemical attack while also being possible microwave dielectrics. Pure MgAl2O4 can be optically ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Ceramics International, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
