Substrate preheating and structural properties of power plasma sprayed hydroxyapatite coatings
(Elsevier Sci Ltd, Oxford, 2016)
The aim of the present study was to investigate the influence of substrate preheating on the structural properties of hydroxyapatite coatings (HACs) deposited by using the high power (52 kW) laminar plasma jet. The deposition ...
Effects of mechanical activation and two-step sintering on the structure and electrical properties of cordierite-based ceramics
(Elsevier Sci Ltd, Oxford, 2016)
The mechanical activation can help reduce production costs and modify cordierite-based materials. In this study, the structure and electrical properties of the mechanically activated MgO-Al2O3-SiO2 system have been analyzed. ...
Bioactive glass-ceramics prepared by powder sintering and crystallization of polyphosphate glass containing strontium
(Elsevier Sci Ltd, Oxford, 2017)
Melt-quenching method was employed for obtaining a glass-ceramic with the following composition 42P(2)O(5). 40CaO.5SrO.10Na(2)O.3TiO(2) (mol%) glass. The crystallization and sintering behavior of glass have been studied ...
Effects of mechanical-activation and TiO2 addition on the behavior of two-step sintered steatite ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Steatite, as ceramic with composition predominantly resting on magnesium silicate, was produced from economic resources - talc, aluminosilicate clays, and either BaCO3 or feldspar as flux. Titanium dioxide was a doping ...
Preparation and characterization of chrome doped sphene pigments prepared via precursor mechanochemical activation
(Elsevier Science Sa, Lausanne, 2013)
Mechanical activation of precursors has been used for the preparation of Cr-doped sphene ceramic pigments (CaTi1-yCrySiO5). Ceramic material has been prepared from a powder mixture of CaCO3, TiO2, SiO2 and Cr(NO3)center ...
Single-stage production of miscanthus hydrochar at low severity conditions and application as adsorbent of copper and ammonium ions
(Elsevier Sci Ltd, Oxford, 2021)
In the framework of bio-circular economy, miscanthus biomass was valorized through a single-stage, low severity hydrothermal carbonization process. The produced hydrochars were characterized using elemental and spectroscopic ...
Surfactant modified zeolites - new efficient adsorbents for mycotoxins
(Elsevier, Amsterdam, 2003)
The in vitro mycotoxins adsorption by natural clinoptilolite-heulandite rich tuff modified with different amounts of octadecyldimethyl benzyl ammonium chloride (Do) and dioctadecyldimethyl ammonium chloride (Pr) was ...
Potentiostatic oxidation of AgCu50 alloy in alkaline solution in the presence of chlorides
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
SEM and EDS analyses of AgCu50 alloy were performed after potentiostatic oxidation in an alkaline solution in the presence or absence of chloride ions. Oxidation in pure alkaline solution was favoured on the portion where ...
Low-temperature Ni-As-Sb-S mineralization of the Pb(Ag)-Zn deposits within the Rogozna ore field, Serbo-Macedonian Metallogenic Province: Ore mineralogy, crystal chemistry and paragenetic relationships
(Elsevier, Amsterdam, 2015)
The Rogozna ore field (ROF) belongs to the Serbo-Macedonian Metallogenic Province (SMMP), and covers a part of the western Dinarides rim and the Vardar ophiolite zone, situated within the Neogene volcanogenic-intrusive ...
Structural features of two novel alluaudite-like arsenates Cd1.16Zn2.34(AsO4)(1.5)(HAsO4)(H2AsO4)(0.5) and Cd0.74Mg2.76(AsO4)(1.5)(HAsO4)(H2AsO4)(0.5)
(Elsevier Science Sa, Lausanne, 2012)
Two new compounds, Cd1.16Zn2.34(AsO4)(1.5)(HAsO4)(H2AsO4)(0.5) (1) and Cd0.74Mg2.76(AsO4)(1.5)-(HAsO4)(H2AsO4)(0.5) (2), have been prepared hydrothermally. Their crystal structures consist of chains of edge-sharing ...
