Pollution of the environment with heavy metals is one of the greatest contemporary problems. Pyrophyllite is a hydrous aluminum silicate, with a wide variety of applications due to its high melting point and stable chemical properties. This study aims to examine the sorption properties of the mechanochemically activated pyrophyllite for the removal...

In this paper, C45 medium carbon tool steel was investigated after various heat treatments. The thermal properties, specifically thermal diffusivity and thermal conductivity, were measured and also the microstructure analysis was done on a light microscope. Heat treatment of the samples included: 1) the normalization heat treatment a...

The mechanical properties and microstructure of copper base shape memory alloys are relatively well known, while data on thermal properties (thermal conductivity, specific heat, and temperature conductivity) are not available. In the frame of our investigation work thermal properties of rapidly solidified Cu-Al-Ni-Mn alloy were deter...

Three new neutral complexes of copper(II) containing chalcone ligands derived from 2'-hydoxyacetophenone and 4-substituted benzaldehydes were synthesized. Complexes were preparedby solution synthesis and characterized by spectroscopy. The catalytic activity of complexes wasexamined in the reaction of 3,5-di-test-butyl catechol (DTBC) oxidation. The...

Pyrophyllite (Al2Si4O10(OH)2) is a layered phyllosilicate mineral with a basic 2:1 crystal structure,consisting of an aluminum octahedral layer placed between two silicon tetrahedral layers (T-O-T),connected by weak Van der Waals forces, which results in easy structural disruption. Naturalpyrophyllite has an electroneutral surface, which causes a h...

Leachate water from sanitary landfills represents one of the most complex global environmentalproblems. This paper examines the possibility of using aluminosilicate material, pyrophyllite, fromthe Parsovići deposit, as an adsorbent. It was researched the influence of two granulations ofpyrophyllite (0-53 μm and 0-100 μm) on the degree of adso...

Metallurgical coke as a fuel, reducing agent and permeable material in high-pressure processes must have pronounced strength and granulation properties due to expected changes in high temperature conditions. The best quality of metallurgical coke is achieved when coal mixtures satisfy a certain range of rheological parameters. The characterization ...

The ore consolidation process is a thermal process and it happens at the temperatures of the ore melting beginning, allowing the ore grains, additives and fluxes to be connected into a solid piece of sinter. The amount of carbon in the sinter mixture and the FeO content of the produced sinter affect the mechanical resistance of the sinter. Indicato...
