Characterization of Mechanochemically Synthesized CaO·ZnO/K2O Mixed Oxides
(Belgrade : Serbian Ceramic Society, 2012)
Room temperature ball milling of CaO and ZnO powder mixture (using molar ratio of CaO:ZnO of 1:2) with the addition of stoichiometrically required amount of water to form calcium zinc hydroxide hydrate (CaZn2(OH)6•2H2O) ...
Mechanochemical preparation and characterization of CaO·ZnO used as catalyst for biodiesel synthesis
(Elsevier, 2012)
In this study, the synthesis of biodiesel or fatty acid methyl esters (FAME) from sunflower oil and methanol using CaO·ZnO catalyst was investigated. Catalyst was synthesized by ball milling of Ca(OH)2 and ZnO powder mixture ...
Kreiranje morfologije i veličine čestica ZnO prahova
(Beograd : Savez inženjera i tehničara Srbije, 2012)
U ovom tekstu objašnjeni su postupci sinteze prahova ZnO i mogućnosti da se tim sintezama morfologija i srednja veličina čestica kreiraju od mikrometarskih štapića do nanometarskih sfernih čestica. Primenjene su dve metode ...
Mechanochemical Preparation of CaO·ZnO – catalyst for Fatty Acids Methyl Esters Synthesis
(Belgrade : Serbian Ceramic Society, 2012)
One of the catalysts that show excellent activity in the methanolysis of vegetable oil under moderate reaction conditions is the mixture of CaO and ZnO oxides. In this study CaO•ZnO catalyst was synthesized by mechanochemical ...
Controlled hydrothermal processing of ZnO powders in the presence of PVP
(Belgrade : Society of Physical Chemists of Serbia, 2012)
In this study low-temperature hydrothermal processing was used for synthesis of ZnO powders with controlled morphology, from micro rods, via hexagonal prism-like to nano-spheres, by varying [Zn2+]/[OH-] molar ratio. The ...
Hydrothermal synthesis of ZnO powders with a tailored particle morphology and improved optical characteristics
(Belgrade : Materials Research Society of Serbia, 2012)
ZnO represent one of the most important multifunctional materials. Its properties are well known and confirmed in different application areas such as: gas sensors, UV lasers, solar cells, electroluminescent and optoelectronic ...
Influence of particle size and morphology of ZnO powders on their optical properties
(Belgrade : Serbian Ceramic Society, 2012)
In this work we present details of different synthesis procedures for preparation of ZnO powders and a possibility to create various particles morphology and average size; from micrometer rods to nanometer spherical ...
Influence of mechanical activation on electrical properties of barium–zinc–titanate ceramics sintered at 1100°C
(Springer US, 2012)
Starting mixtures of BaCO3, ZnO, and TiO2 powders are mechanically activated in a planetary ball mill for various periods of time. The powders obtained are sintered isothermally at 1100°C for 120 min. Non-isothermal sintering ...
