Effect of thermal treatment on mechanically milled cobalt powder

Author: Bolokang, AS ; Phasha, MJ ; Camagu, ST ; Motaung, DE ; Bhero, S Date: Mar 2012 Stabilization of the metastable FCC phase has been achieved after 10 h milled Co powder sintering at 1400 °C. Phase identification of the Co powders was performed by the X-ray diffraction analysis, while the microstructural analyses were ... Read more
Mechanical alloying and sitering of TI - 10WT.% MG powders

Author: Machio, Christopher N ; Nyabadza, D ; Chikwanda, HK ; Phasha, M ; Sibanda, VM Date: Jun 2009 A Ti-10wt.%Mg powder alloy has been produced by mechanical alloying. Elemental powders of Ti and Mg were ball milled in a Zoz-Simoloyer CM01 for 16 and 20 hours under argon. Mechanical alloying was followed by XRD, SEM and particle size ... Read more
Raney copper catalysts for the water-gas shift reaction - II. Initial catalyst optimisation

Author: Mellor, JR ; Coville, NJ ; Sofianos, AC ; Copperthwaite, RG Date: 23 Dec 1997 The initial Raney copper WGS activity based on catalyst volume has been shown to be comparable to industrial and co-precipitated alternatives under varying reaction conditions. The presence of zinc oxide in the Raney copper structure was shown ... Read more
Raney copper catalysts for the water-gas shift reaction: I. Preparation, activity and stability

Author: Mellor, JR ; Coville, NJ ; Sofianos, AC ; Copperthwaite, RG Date: 23 Dec 1997 Characterisation of partially leached Raney copper catalysts demonstrated that the chemical nature of the reactant surface could be determined by controlling the leaching process. Initial water-gas shift (WGS) activity of the Raney copper ... Read more
