BaTiO3 – ceramics and Fractal Microstructure Analyses
(Belgrade : Serbian Ceramic Society, 2014)
Ceramics grain structure is difficult to describe by using traditional analytical methods based on Euclidean geometry. Using the fractal geometric/analytic methods instead, the new approach is offered in this paper. There ...
Ag&ZnO Obtained by Solvothermal Method for Photocatalytic Applications
(Belgrade : Serbian Ceramic Society, 2014)
In this work is reported the solvothermal synthesis of hybrid nanostructured ZnO&Ag systems starting from zinc nitrate hexahydrate (Zn(NO3)2•6H2O) and silver nitrate (Ag(NO3)2) as precursors. The structural and morphological ...
Influence of Sm2O3 on the Microstructure and Dielectric Characteristics of Codoped BaTiO3 Ceramics
(Belgrade : Serbian Ceramic Society, 2014)
The samples of Sm/Mn codoped BaTiO3 ceramics, prepared by conventional solid state procedure with dopant concentrations ranged from 0.1 up to 5.0 at%, were investigated in this paper. The specimens were sintered at 1290°C ...
Towards Electronic Materials Fractal Theory
(Belgrade : Serbian Ceramic Society, 2014)
We are witnesses of blowing-up of new technologies and materials that nowadays are being introduced by the increasing rate. With huge diversity of electrophysical properties as well as difference between dimensions of 12 ...
Targeted Synthesis of Ceramic-Polymer Nanocomposites
(Belgrade : Serbian Ceramic Society, 2014)
It is well known that materials used in nano-electro-mechanical systems (NEMS) must simultaneously satisfy numerous requirements for chemical, structural, mechanical and electrical properties. Taking into account that the ...
Influence of Mechanical Activation on the Constituents of the MgO-Al2O3-SiO2-MoO3 System
(Belgrade : Serbian Ceramic Society, 2014)
Cordierite, 2MgO•2Al2O3•5SiO2 (MAS), is high-temperature ceramic material. Cordierite is commonly used material because of outstanding electrical properties, low temperature expansion coefficient and low dielectric constant. ...
The Electrical Characteristics of Nb doped BaTiO3 Ceramics
(Belgrade : Serbian Ceramic Society, 2014)
The Nb doped BaTiO3 ceramics, with different Nb2O5 content, ranging from 0.5 to 2.0 at% Nb, were investigated regarding their electrical characteristics in this paper. Nb/BaTiO3 ceramics using in this investigation were ...
Advanced Optimization of Heavy Clay Products Quality by Using Artificial Neural Network Model
(Belgrade : Serbian Ceramic Society, 2014)
The effects of firing temperature (800–1100°C), chemical composition (expressed in terms of the content of major oxides - SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, MnO and TiO2), as well as several shape formats of laboratory ...
The Ho2O3 Concentration Influence on BaTiO3 – ceramics Fractal Structures
(Belgrade : Serbian Ceramic Society, 2014)
An influence of dopant concentration on microstructure and dielectric properties of doped BaTiO3-ceramics is developed based on fractal geometry. Using different technological parameters and different additives the structure ...
