Influence of mechanical activation on microstructure and crystal structure of sintered MgO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2010)
Mixtures of MgO-TiO2 were mechanically activated using high-energy planetary ball mill during 5, 10, 20, 40, 80 and 120 minutes. Sintering process was preformed in air at 1100o-1400oC for 2h. The decrease in powder’s ...
Influence of mechanical activation on functional properties of barium hexaferrite ceramics
(Elsevier, 2018)
Barium hexaferrite ceramics were prepared using mechanically activated mixtures of iron and barium titanate. The 60:40 mass% Fe:BaTiO3 powder mixtures were mechanically activated for different times (100–240 min) and ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Elsevier, 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 ...
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 ...
Sintering of cordierite in the presence of MoO3 and crystallization analysis
(Belgrade : International Institute for the Science of Sintering, 2014)
Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400ºC). Because a low temperature process is desirable, it is necessary to find functional ads which can allow easier ...
Advantages of combined sintering compared to conventional sintering of mechanically activated magnesium titanate
(Belgrade : International Institute for the Science of Sintering, 2014)
In this article, the advantages of combined sintering in comparison with the conventional one, of mechanically activated magnesium titanate ceramic were investigated. The stoichiometric mixtures of MgO and TiO2 were ...
