Theoretical and experimental study of polycrystalline phases obtained by the nanometric ZnTiO3 powder sintering
(Belgrade : Institute for Multidisciplinary Research, 2019)
In this study we have combined two research methods: structure prediction of ZnTiO3 using computational SPuDS software, and the characterization of binary oxides obtained from ZnO TiO2 system. Pure nanosized ZnTiO3 (99.5%), ...
The effect of ball milling on properties of sintered manganese-doped alumina
(Elsevier, 2019)
Alumina-based compounds have many technological applications and attract great attention even after decades of investigation, due to their good chemical, electrical, and mechanical properties. A mixture of several alumina ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Synthesis of barium-zinc-titanate ceramics
(Belgrade : International Institute for the Science of Sintering, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
Hydroxyapatite nanopowders prepared in the presence of zirconium ions
(Elsevier, 2014)
Hydroxyapatite nanopowders were prepared in the presence of different concentrations of zirconium ions. Such crystallization conditions yielded significantly reduced particle size and increased specific surface area. Cell ...
Electrical Characteristics of Ho doped BaTiO3 Ceramics
(Belgrade : Serbian Ceramic Society, 2019)
In this paper, electrical characteristics of Ho2O3 doped BaTiO3 ceramics were shown, using new method for measuring samples. The BaTiO3 doped samples were sintered at 1320°C for 4 hours. The concentration of the additives ...
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 ...
Influence of mechanochemical activation on sintering of cordierite ceramics with the presence of Bi2O3 as a functional additive
(Belgrade : Materials Research Society of Serbia, 2011)
According to its exceptional electrical characteristics, such as low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO⋅2Al2O3⋅5SiO2, represents very attractive ...

Reaction kinetics of mechanically activated cordierite based ceramics studied via DTA
(Ljubljana : Central and Eastern European Committee for Thermal Analysis and Calorimetry, 2015)
Cordierite, 2MgO•2Ah03•5Si02 (MAS), is a very attractive high-temperature ceramic material. In order to accelerate the process of sintering, 5.00 mass% Mo03 was added to the starting mixtures. The mechanical activation of ...
