Fractal nature Heywang model contribution and BaTiO3-ceramics semiconducting phenomena
(Belgrade : Serbian Ceramic Society, 2018)
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 ...
Microstructure evolution and sintering kinetics of ZnO
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The aim of this paper was to analyse the sintering kinetics and microstructure evolution of ZnO. Powder was isothermally sintered (15, 30, 60, 90 and 120 minutes) in the temperature range from 800 to 1200oC. The values of ...
Science of Sintering in the XXI Century : book of abstracts / X World Round Table Conference on Sintering
(Belgrade : Institute of Technical Sciences of SASA; International Institute for the Science of Sintering; Serbian Academy of Sciences and Arts, 2002)
Science of Sintering in the XXI Century : book of abstracts / X World Round Table Conference on Sintering [3-6 September 2002 Belgrade, Yugoslavia] ; [organized by] Serbian Academy of Sciences and Arts and International ...
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 ...
The Influence of Mechanical Activation on Sintering Process of BaCO3-SrCO3-TiO2 System
(Belgrade : Serbian Ceramic Society, 2012)
In this article the influence of mechanical activation on sintering process of barium-strontiumtitanate ceramics has been investigated. Both non-activated and mixtures treated in planetary ball mill for 5, 10, 20, 40, 80 ...
Synthesis, characterization and sintering properties of Zr-doped hydroxyapatite
(Belgrade : Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2011)
Improving of material characteristics could be achieved in different ways, but it is always connected with the issue of impairing the other functional properties. Hydroxyapatite bioceramics lacks of insufficient mechanical ...
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 ...
