Contribution of Frenkel's theory to the development of materials science
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
The original and comprehensive research of Yakov Rich Frenkel in physics and physical chemistry of condensed states, nuclear physics, electrodynamics, science of sintering has significantly contributed to the development ...
Physical Properties of Sintered Alumina Doped with Different Oxides
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
Corundum (alpha-alumina) is a suiTab. material for usage in various industry fields owing to its chemical stability, electrical and mechanical features. It is known that properties of ceramics could be modified by addition ...
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 ...
Sintering of Fly Ash Based Composites with Zeolite and Bentonite Addition for Application in Construction Materials
(Međunarodni Institut za nauku o sinterovanju, Beograd, 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
(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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
