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 ...
Sintering of fly ash based composites with zeolite and bentonite addition for application in construction materials
(International Institute for the Science of Sintering, 2017)
Due to pozzolanic characteristics, fly ash is commonly used as a cement replacement in construction composites. Addition of natural clays with sorption ability (i.e. zeolite and bentonite) in to the fly ash based construction ...

Poster presented at the Adriatic School of Nanoscience – ASON-1, Dubrovnik, Croatia, September 19–23, 2010
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 ...
Microstructure changes caused by thermal etching of sintered ZnTiO3
(2014)
Polishing and thermal etching was performed on ZnTiO3sintered ceramic. Two set of specimens were recorded, on higher 1200oC/1100oC sintered/etched, and lower 900oC/800oC sintered/etched. Phase composition, crystallite sizes ...
Analysis and modeling of sintering of Sr-hexaferrite produced by PIM technology
(Belgrade : International Institute for the Science of Sintering, 2011)
The powder injection moulding (PIM) technology is lately becoming more and more significant due to complex design possibilities and good repeatability. This technology requires optimization of all steps starting with ...
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 ...
3 Structural, morphological and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Starting nanopowders of TiO2 (anatase 99.7%) and a-Fe2O3 (hematite) were mixed in the weight ratio 60:40 and 40:60. Green samples were sintered in the temperature range 750-1250oC in air. Structural, morphological and ...
Structural analyses of sintered MT and BZT ceramics
(Belgrade : Serbian Society for Microscopy, 2010)
Development of dielectric materials is increasing with a rapid progress in mobile and satellite communications systems, where magnesium titanates find their place owing to good dielectric properties. Recently it has been ...
