Electrical Properties and Microstructure Fractal Analysis of Magnesium-Modified Aluminium-Silicate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
The addition of Mg(2)(NO)(3) and some active additives, composed of Al salts, to the mixtures of kaolinite and bentonite can provide clay compositions which, after sintering at high temperatures, produce very porous ceramics ...
Isothermal kinetics of titanium-oxo-alkoxy clusters formation
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
In this article, the influences of titanium tetraisopropoxide Ti(OR)4 (R = Pri) concentration, molar ratio, h = [H2O]/[Ti(OR)4], and temperature, on the formation kinetics of the titanium-oxo-alkoxy clusters (TOAC), were ...
Electrical Properties of Magnesium Titanate Ceramics Post-Sintered by Hot Isostatic Pressing
(Međunarodni Institut za nauku o sinterovanju, Beograd, 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 ...
Structure and photocatalytic properties of sintered TiO2 nanotube arrays
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by electrochemical oxidation of titanium foil in an acid electrolyte. In order to alter the crystallinity and the morphology of films the ...
Effect of Chemical Composition on Microstructural Properties and Sintering Kinetics of (Ba,Sr) TiO3 Powders
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
Barium strontium titanate powders with different Ba: Sr ratios were investigated to determine the influence of the initial composition of powder mixture on microstructural properties and sintering kinetics. It was determined ...
Characterization of FeCoV Alloy Processed by PIM/MIM Route
(Međunarodni Institut za nauku o sinterovanju, Beograd, 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 ...
Microstructure and Phase Composition Of Steatite Ceramics Sintered by Traditional and Spark Plasma Sintering
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
The influence of the sintering method on the mineral phase transformations and development of the crystalline microstructure of steatite ceramics was investigated. The steatite samples were fabricated from talc and bentonite ...
Synthesis and Sintering of High-temperature Composites Based on Mechanically Activated Fly Ash
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Amount of fly ash which is and yet to be generated in the coming years highlights the necessity of developing new methods of the recycling where this waste can be reused in significant quantity. A new possibility for fly ...
Characterisation of Mn0.63Zn0.37Fe2O4 Powders After Intensive Milling and Subsequent Thermal Treatment
(Međunarodni Institut za nauku o sinterovanju, Beograd, 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 ...
Formation of Porous Wollastonite-based Ceramics after Sintering With Yeast as the Pore-forming Agent
(Međunarodni Institut za nauku o sinterovanju, Beograd, 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, ...
