Phase transformations and thermal effects of mechanically activated BaCO3 -TiO2 system
(Ferroelectrics, 2002)
Phase transformations and thermal effects of BaTiO 3 ceramics due to influence of mechanical activation were investigated. Equimolar mixture of BaCO 3 and TiO 2 powders was activated in high energy vibromill for various ...
Flowability of electrolytic copper powder
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The surface structure of powder particles, which allows free flow of copper powder, was examined. It has been shown that a sufficiently dense surface structure which permits free flow will be obtained if apparent density ...

In this paper rye present the data on the disease intensity of the tomato plants grown in glass and plastic-houses, and in the open field. The infection was caused by the following viruses: Tomato mosaic virus (ToMV), ...
The effect of reversing current on the properties of copper and electrolytic copper powder. I. The morphology of powder particles
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The selective dissolution of copper dendrites during electrodeposition by reversing current was discussed and the effects on the morphology of copper powder particles were elucidated.
New digital method of microstructural characterization of sintered materials
(Serbian Acad Sciences Arts, Belgrade, 2002)
Since a lot of physical properties of novel materials are determined by their microstructure it is very important to predict and control materials microstructure and its evolution, both in technological process of material ...
