Sintering of defect-free functionally graded biomaterials
(Belgrade : Materials Research Society of Serbia, 2011)
Functionally graded materials (FGMs) with a gradient of chemical, electrical, mechanical and/or biological properties are very attractive because of their superior features compared to conventional materials. It is known ...
Effect of consolidation parameters on structural, microstructural and electrical properties of magnesium titanate ceramics
The aim of this study is to explore the influence of the processing route on the structural and physical properties of bulk MgTiO3 ceramics. Commercially available MgO and TiO2 powders were mechanically activated in a ...
Effects of mechanical-activation and TiO2 addition on the behavior of two-step sintered steatite ceramics
Steatite, as ceramic with composition predominantly resting on magnesium silicate, was produced from economic resources – talc, aluminosilicate clays, and either BaCO3 or feldspar as flux. Titanium dioxide was a doping ...
Microstructural changes initiated by sintering of refractory concrete based on recycled bauxite aggregate
(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, 2012)
Concretes whose structure and final properties are shaped during thermal pre-treatment or during life-service at elevated temperatures can be applied as construction material for thermal insulation and/or refractory linings ...
Characterisation of Mn0.63Zn0.37Fe2O4 powders after intensive milling and subsequent thermal treatment
(Science of Sintering, 2017)
Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. The goal was to observe intensive milling influences on oxidation and reduction processes ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3
Poster presented at the conference Advanced Ceramics and Application II – Serbian Ceramic Society, Belgrade, September 30 – October 1, 2013
Inert atmosphere processing of hydroxyapatite in the presence of lithium iron phosphate
(Journal of the European Ceramic Society, 2018)
The present study describes sintering behaviour of hydroxyapatite (HAp) upon addition of lithium iron phosphate (LFP) (1-10 wt.%) system in inert (Ar) atmosphere. The interaction between materials and melting of LFP ...
Statistical Analysis of the Influence of Temperature on Microstructure Contact Surfaces on BaTiO3 -ceramics Doped with Ho2O3
(Belgrade : Serbian Ceramic Society, 2014)
The materials based on BaTiO3 can be controlled using different technological parameters and different additives. We investigate the influence of different temperature levels of sintering (1320°C, 1350°C and 1380°C) on the ...
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 ...
