Investigation of mechanism and kinetics of chalcopyrite concentrate oxidation process
(Croatian Metallurgical Society, 2008)
The oxidation process of chalcopyrite concentrate "Rudnik" (Serbia) was investigated by DTA-TG measurements under air conditions in the temperature range of 298 - 1173 K, as well as by XRD analysis of the oxidation products ...
Tensile properties of fiber-resin composites that consist of polyarmid fiber (Kevlar 129) and poly(vinilbutyral) / Zatezna svojstva polimernog kompozitnog materijala poliaramidna vlakna (Kevlar 129) - poli(vinilbutiral)(PVB)
(Savez inženjera metalurgije Srbije, Beograd, 2006)
Thanks to fact that composite material have usefully characteristic two or more materials, they are becoming more and more substitute standard materials in every field of technique they start to. In this study static ...
Characterization of nano-powder morphology obtained by ultrasonic spray pyrolysis
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Spherical nanosized particles of copper were synthesized by ultrasonic dispersion of solutions from copper sulphate in the temperature range of 800-900°C in hydrogen atmosphere. A controlled particle size was realized ...
