Analysis of nonisothermal sintering of zinc-titanate ceramics doped with MgO
(Springer, 2008)
The aim of this work is to analyze nonisothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO 2, and MgO (0, 1.25, and 2.5%) are mechanically activated for 15 ...
Influence of mechanical activation on electrical properties of barium–zinc–titanate ceramics sintered at 1100°C
(Springer US, 2012)
Starting mixtures of BaCO3, ZnO, and TiO2 powders are mechanically activated in a planetary ball mill for various periods of time. The powders obtained are sintered isothermally at 1100°C for 120 min. Non-isothermal sintering ...
Synthesis and Characterization of Multifferoics 16%(Fe2O3)4%(BaCO3)80%(BaTiO3)
(Belgrade : Serbian Ceramic Society, 2017)
The initial powder (16 % Fe2O3, 4 % BaCO3, 80 % BaTiO3) was mechanically activated in a planetary mill for 20, 80, 120, 160, 200 and 220 minutes in air. Modified Faraday method was used to perform magnetization measurements ...
Electronic Properties of BZT Nano-Ceramic Grades at Low Frequency Region
(Belgrade : Serbian Ceramic Society, 2021)
Barium zirconium titanate ceramics were prepared using solid state reactions of BaCO3, TiO2 and ZrO2 at elevated temperatures. The prepared BZT was mechanically activated in the planetary ball mill from 0-120 min to achieve ...
Sintering effects on microstructure and dielectric properties of CCTO ceramics
(Belgrade : Materials Research Society of Serbia, 2012)
A perovskite-type compound, calcium copper titanate (CaCu3Ti4O12, CCTO) attracted ever increasing attention for its practical applications in microelectronics, especially for preparation of capacitors and memory devices. ...
DSC-TG-MS study of hydroxyapatite nanopowders
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Hydroxyapatite nanopowders have been widely studied for biomedical application due to excellent biocompatibility. It attaches chemically to bone tissue providing fixation of artificial implant materials. Main research ...
Application of the master sintering curve theory to non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
In this paper a practical approach to the analysis of sintering of BaTiO3 using the Master Sintering Curve concept has been presented. Non-isothermal sintering of high-purity non-doped BaTiO3 ceramics was monitored using ...
Structural properties of FeCoV alloys produced by PIM / MIM technology
(Belgrade : Serbian Ceramic Society, 2022)
FeCoV alloys with high saturation magnetization and high Curie temperature, making them useful for high-temperature and power-dense applications (e. g. aviation device). In this study, we report the results of observing ...
Sintering and Phase Transition of the ZnTiO3 Nano Powder Dilatometric Data Deconvolution
(Belgrade : ETRAN SocietyBelgrade : Academic Mind, 2022)
Sintering and phase transition are often superimposed at dimensional change diagram recorded during heating. Phase transition kinetic is thus hard to deconvolute due to the superposition of the sintering and phase transition ...
Multi-phase (Zr,Ti,Cr)B2solid solutions: Preparation, multi-scale microstructure, and local properties
(Tsinghua University Press, 2023)
Multi-phase ceramics based on ZrB2, TiB2 and doped with CrB2 and SiC were prepared by powder metallurgy and hot pressing to explore the possibility of obtaining multi-scale microstructures by super-saturation of complex ...
