Influence of different bonding and fluxing agents on the sintering behavior and dielectric properties of steatite ceramic materials
(Elsevier, 2017)
The focus of the study was on providing insights into interconnections between sintering and development of the crystalline microstructure, and consequently variations in dielectric behavior of four steatites fabricated ...
Mechanical properties and microstructure fractal analysis of refractory bauxite concrete
(Belgrade : International Institute for the Science of Sintering, 2015)
The surface topography analysis via fractals as a means of explanation of composite materials mechanical and microstructural characteristics has hardly been reported so far. This study proposes a method of fractal analysis ...
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 ...
Structural analyses of sintered MT and BZT ceramics
(Belgrade : Serbian Society for Microscopy, 2010)
Development of dielectric materials is increasing with a rapid progress in mobile and satellite communications systems, where magnesium titanates find their place owing to good dielectric properties. Recently it has been ...
Sintering of mechanically activated Zno-TiO 2 powders
(Springer, 2008)
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...
Electret state in Bi4Ti3O12 ceramics
(Elsevier, 2010)
The effect of thermal treatment atmosphere (argon, air or oxygen) on the electret behavior of bismuth titanate (Bi4Ti3O12) ceramics was investigated. Polycrystalline ferroelectric ceramics were prepared by reactive liquid ...
Characterisation of Mn0.63Zn0.37Fe2O4 powders after intensive milling and subsequent thermal treatment
(Belgrade : Serbian Ceramic Society, 2016)
Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. Powders were characterized with XRD, SEM and particle seizer. Subsequent heating was monitored ...
Modeling, designing and processing of barium titanate stannate
(Belgrade : Serbian Ceramic Society, 2016)
Barium titanate stannate (BTS, BaTi1−xSnxO3) functionally graded materials (FGMs) with an
uniaxial Ti/Sn concentration gradient are very useful for applications in electroceramics, due
to a high dielectric constant in a ...
Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of γ to α phase transformation mechanism
(Elsevier, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
Phase Formation at the Sintering of Sa, Zn, Ti Oxides
(Kiev, 2009)
Complex compounds with oxide phases of Ba, 2n, and 11 are widely used in instrument engineering. It is also important to find such production routes for ceramics, which provide their stable structure and properties. Phase ...
