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 ...
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 ...
