Analysis of early-stage sintering mechanisms of mechanically activated BaTiO3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Barium-titanate powder was mechanically activated in a planetary-ball mill for 60 and 120 minutes. Non-isothermal sintering of non-activated and activated powder samples was investigated using a dilatometer in the temperature ...
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 ...
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 ...
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 ...
Synthesis of Barium-zinc-titanate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
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 ...
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 ...
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 ...
