Synthesis and dielectric properties of calcium copper titanate (CCTO) based ceramics
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The perovskite CaCu3Ti4O12 (CCTO) powders with various oxide phase impurities were synthesized via citric gel combustion method. Influence of citric acid amount used for gel preparation was examined in order to lower CCTO ...
Influence of different pore-forming agents on wollastonite microstructures
(Belgrade : Serbian Ceramic Society, 2016)
In this study, highly porous macro- and micro-cellular wollastonite-based ceramics was synthesized. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min ...

Recently, with the huge use of smart gadgets, developing of smart jewelry represents a very interesting segment in material science, as well as in electronic science. Alumina is widely used ceramic in many industrial fields ...
Formation of porous wollastonite-based ceramics after sintering with yeast as the pore-forming agent
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, synthesis of porous wollastonite-based ceramics was reported. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min of ultrasound treatment, ...
Reheating of zinc-titanate sintered specimens
(Belgrade : International Institute for the Science of Sintering, 2015)
The scope of this work was observing dimensional and heat transfer changes in ZnTiO3 samples during heating in nitrogen and air atmosphere. Interactions of bulk specimens with gaseous surrounding induce microstructure ...
Adsorption capacity of wollastonite based adsorbents with porous structure controlled with different progeny agents
(Belgrade : Serbian Ceramic Society, 2016)
Porous wollastonite (WL) based adsorbents were fabricated by a pressureless sintering process by using low molecular weight poly(methyl methacrylate) (PMMA), nanocellulose (NC) and yeast as the pore forming agents. WL based ...

Well known material with ferroelectric properties, BaTiO3-ceramics, have many advanced applications. Fractal approach in analyzing of these structures can be one of the solution for investigation of morphology. It is known ...
The influence of powder characteristics on two-step sintering behavior of hydroxyapatite
(Belgrade : Institute of Technical Sciences of SASA, 2010)
Fabrication of full dense ceramic materials on the basis of hydroxyapatite (HAp) and biphasic calcium phosphate (BCP) with controllable microstructural and compositional characteristics attracts considerable efforts. Various ...
Barium-zinc-titanate ceramics
(Kiev : National Academy of Sciences of Ukraine (NASU); Frantsevych Institute for Problems of Materials Science of NASU; National Technical University of Ukraine "KPI"; Ukrainian Materials Science Society; INTEM LTD, 2010)
Starting mixtures of BaCO3, ZnO and TiO2 powders were mechanically activated in a planetary ball mill for various periods of time. The powders obtained were sintered nonisothermally to temperatures between 1100 and 1300°C ...
Structural characterization and electrical properties of sintered magnesium-titanate ceramics
(Belgrade : Materials Research Society of Serbia, 2012)
In this article the influence of ball milling process on structure of MgO-TiO2 system, along with its influence on electrical properties of post-sintering samples, were investigated. Mixtures of MgO-TiO2 powders were ...
