The Influence of Mechanical Activation on Sintering Process of BaCO3-SrCO3-TiO2 System
(Belgrade : Serbian Ceramic Society, 2012)
In this article the influence of mechanical activation on sintering process of barium-strontiumtitanate ceramics has been investigated. Both non-activated and mixtures treated in planetary ball mill for 5, 10, 20, 40, 80 ...
Structural analysis of Zn2TiO4 doped with MgO
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
Intrinsic resistivity of sintered Nickel Manganite vs. powder activation time and density
(Belgrade : International Institute for the Science of Sintering, 2008)
In this work the DC resistivity of sintered nickel manganite NiMn2O4 (NTC thermistor material) was studied as a function of additional powder activation time in a planetary ball mill (0, 5, 15, 30, 45 and 60 min). The ...
Analysis of the initial-stage sintering of mechanically activated SrTiO3
The initial-stage of sintering plays a significant role in determining the final microstructure that defines the main characteristics of electroceramics materials such as functional properties. In this article non-isothermal ...
Influence of one activated component on the sintering process of three phase system
(Belgrade : Materials Research Society of Serbia, 2013)
According to its low temperature thermal expansion coefficient, low dielectric constant, also good mechanical properties, cordierite, 2MgO×2Al2O3×5SiO2, represents a very attractive hightemperature ceramic material. In ...
Sintering of Zinc-Titanate
(Atlantis Press, 2016)
Sintering kinetics of the mechanically activated ZnO-TiO2 system was studied. Mixtures of ZnO and TiO2 powders were mechanically activated using a high-energy ball mill for different time intervals from 0 to 300 min. Formal ...
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
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 ...
Processing and properties of dense cordierite ceramics obtained through solid-state reaction and pressure-less sintering
(Taylor and Francis, 2019)
Sintering of pure cordierite 2MgO:2Al2O3:5SiO2, and cordierite with the addition of 5 mass % TeO2 was studied. Green bodies were prepared from powder mixtures mechanically activated in a high-energy planetary mill, shaped ...
