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 ...
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 ...
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 ...
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 ...
The crystal structure, microstructure, and dielectric properties of BaTi1-xSnxO3 (x = 0,0.05 and 0.1) ceramics sintered in different atmospheres (air and Ar)
(Belgrade : Institute of Technical Sciences of SASA, 2015)
Due to specific dielectric and ferroelectric properties, functional ceramics based on barium titanate (BaTiO3) have found application in semiconductor industries. Appropriate electrical properties of barium titanate-based ...
Fractal corrections of BaTiO3-ceramic sintering parameters
(Belgrade : International Institute for the Science of Sintering, 2014)
Morphology of ceramics grains and pores as well as Brownian character of particle dynamics inside ceramics specimen contributes to better understanding of the sintering process. BaTiO3-ceramics, studied in this paper, has ...
Microwave Electro Ceramic Based on Magnesium Titanate Compounds
(Paris : Atlantis Press, 2017)
The intensive progress in electronics, especially telecommunication and mobile phone in 1990s, was the main driving force for the extensive research and development of microwave ceramics. These materials are often used in ...
Environmental Aspects of Red Mud and Its Utilization as a Component of Building Materials
(Paris : Atlantis Press, 2017)
The Bayer process is the main industrial process covering 90 % of global production of alumina. The sintering process deals with the medium and low grades of bauxite resource. During the alumina production process, red mud ...
Mechanically activated coal ash as refractory bauxite shotcrete microfiller: Thermal interactions mechanism investigation
(Elsevier, 2014)
A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...
Structural characterization and electrical properties of sintered magnesium–titanate ceramics
(Elsevier, 2013)
In this article the influence of ball miling process on structure of MgO–TiO2 system, as well as the electrical properties of samples after sintering, was investigated. The mixtures of MgO–TiO2 powders were mechanically ...
