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 ...
Two step sintering of ZnTiO3 nanopowder
(Belgrade : International Institute for the Science of Sintering, 2017)
Metastable nanopowder ZnTiO3 was pressed into cylindrical compacts at 200 MPa. Compacts were treated by conventional heating with isothermal holding at 931°C for 10 minutes, 25 minutes and 40 minutes. ZnTiO3 compacts were ...
Discrete temperature values in the sintering process as a BaTiO3-ceramics properties parameter
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, we develop the new physical-mathematical time scale approach-model applied to BaTiO3-ceramics. At the beginning, a time scale is defined to be an arbitrary closed subset of the real numbers R, with the ...
Formation of porous wollastonite-based ceramics after sintering with yeast as the pore-forming agent
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, synthesis of porous wollastonite-based ceramics was reported. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min of ultrasound treatment, ...
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 ...
Electrical properties of magnesium titanate ceramics post-sintered by hot isostatic pressing
(Belgrade : International Institute for the Science of Sintering, 2017)
Post-sintering of magnesium titanate ceramics by hot isostatic pressing (HIP) in an oxygen-free atmosphere significantly alters various electrical properties of the product. In particular, the sintered material becomes a ...
Characterization of FeCoV alloy processed by PIM/MIM route
(Belgrade : International Institute for the Science of Sintering, 2017)
In this study the characterization of FeCo-2V alloys toroidal samples produced by PIM/MIM technology was presented. The feedstock for metal injection molding (MIM) was prepared by mixing starting FeCoV powder with a low ...
