Fractal nature Heywang model correction and Brownian motions
(Belgrade : Serbian Ceramic Society, 2017)
Ceramics grains contacts are essential for understanding complex dielectric properties of electronic ceramics materials. Since the actual contact surface is an irregular object, the theory of fractal sets is applied. Also, ...
Synthesis of ZnO:Ag core-shell nanoparticles with enhanced photocatalytic properties by single - and two-steps USP
(Belgrade : Serbian Ceramic Society, 2017)
Synthesis of ZnO:Ag core-shell nanoparticles were performed by ultrasonic spray pyrolysis (USP) from the corresponding nitrate solutions. Varying relative concentrations of Ag and ZnO precursors and two different equipment ...
Fluorine doping of cathode materials for rechargeable batteries
(Belgrade : Serbian Ceramic Society, 2017)
In the continuing search for alternative cathode materials for rechargeable batteries with improved electrochemical performances, there is a need for a versatile approach that will address concerns regarding low reversible ...
Generalized Lorentz model description of electrical, dielectric, conductive and magnetic processes two-time relaxations in BaTiO3 ceramics with constitutive relations
(Belgrade : Serbian Ceramic Society, 2017)
In this study, generalized Lorentz model is considered in the framework of dielectric, conductive and/or magnetic responses of materials. Beside positive temperature coefficient of resistivity (PTCR) materials (current ...
New aspects in processing of hydroxyapatite ceramics
(Belgrade : Serbian Ceramic Society, 2017)
Sintering of hydroxyapatite ceramics has been a challenging topic for decades since the material has good bioactivity, proven biocompatibility, low cost, and high availability. Besides its biomaterial applications, ...
Copmarative analysis of mortars from the archeological sites Gamzigrad (Romuliana) and Caričin Grad for the purpose of making compatible repair mortars
(Belgrade : Serbian Ceramic Society, 2017)
The paper presents a comparative analysis of mortars found at two significant archeological sites in Serbia. Specifically, those are Gamzigrad (Romuliana) near Zajecar and the archeological site Caricin Grad near Leskovac. ...
Dilatometer as a scientific tool
(Belgrade : Serbian Ceramic Society, 2017)
Dilatometry is defined as the dimensional change of a solid specimen recorded during temperature schedule. Set of data obtained in such a manner are known as dilatogram. Dilatograms for different sort of materials represent ...
Preparation of cordierite-based adsorbents for water purification
(Belgrade : Serbian Ceramic Society, 2017)
In this study, porous cordierite-based ceramics was synthesized. In the first step, MgO, Al2O3, and SiO2 (all Aldrich, p.a.) were used. MgO and Al2O3 powders were calcined at 1000 oC for 2 h, in order to avoid hydroxides. ...
Fractals and ceramics materials characterization
(Belgrade : Serbian Ceramic Society, 2017)
Large part of powder based materials; especially ceramics are porous in more or less percentage. For such materials, two separated spaces are present. The “positive” space is made by grains or particles, while the “negative” ...
Influence of synthesis parameters and thermal treatment on functional properties of Fe3O4-BaTiO3 multiferroics obtained by mechanical activation
(Belgrade : Serbian Ceramic Society, 2017)
Mechanical activation of a mixture of polycrystalline powders Fe3O4 (50% wt.) and BaTiO3 (50% wt.) was performed in a planetary ball-mill, with different milling times (3 h, 6 h and 12 h). Average crystallite size determined ...
