Multiferroic Heterostructure BaTiO3/ε-Fe2O3 Composite Obtained by in situ Reaction
(Belgrade : International Institute for the Science of Sintering, 2021)
Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared ...
A phenomenological analysis of sintering kinetics from the viewpoint of activated volume
(Belgrade : International Institute for the Science of Sintering, 2005)
The sintering kinetics of real systems has been viewed as a process of transport of activated volume. Activated volume is a parameter that can be used to describe mass transport during the sintering process. It defines the ...
Mechanical-chemical synthesis Ba0.77Sr0.23TiO3
(Belgrade : International Institute for the Science of Sintering, 2012)
Barium-Strontium-Titanate Ba0.77Sr0.23TiO3 was prepared from starting materials BaCO3, SrCO3 and TiO2 through solid-state reactions. Mixtures of these oxides are mechanically activated in a high-energy planetary ball mill ...
Electrical properties and microstructure fractal analysis of magnesium-modified aluminium-silicate ceramics
(Belgrade : International Institute for the Science of Sintering, 2011)
The addition of Mg2(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 ...
Study of Nanosized Hydroxyapatite Material Annealing at Different Retention Times
(Belgrade : ETRAN, 2020)
The aim of the study was to investigate the influence of low heating temperatures with two different retention times to optimize the process for obtaining nanosized hydroxyapatite material that can possibly be used in the ...
Effects of Mechanical Activation on the Formation and Sintering Kinetics of Barium Strontium Titanate Ceramics
(Belgrade : ETRAN, 2020)
