Aluminium oxide . Aluminium oxide is produced from of bauxite; it is crushed, ground, and then leached with sodium hydroxide to form sodium aluminate from which the aluminium hydrate is precipitated and then calcined to produce aluminium oxide (alumina) (ATSDR, 1999; HSDB, 1995).
In this study, cobalt ferrite (CoFe2O4) nanoparticles were synthesized by intensive mechanical alloying of CoCO3 and αFe2O3 powder using a planetary high energy ball mill in air without any subsequent heat treatment. Effects of milling time on the phase composition, morphology and magnetic properties of the powders were evaluated using XRD, FESEM and VSM techniques, respectively.
The production of highpurity aluminum nanoparticles (AlNPs) is challenging due to the highly reactive nature of Al metals. Electromagnetic levitation gas condensation (ELGC) is a promising method to produce highpurity metallic particles as it avoids the interaction between molten metal and refractorylined, which guarantees the removal of impurities such as oxygen (O).
In the present study high energy ball milling was utilized to produce aluminum (Al6061) matrix nanocomposite powders reinforced with nanosilicon carbide (SiC) particles. The starting materials containing different percentages (1,3 or 5 wt.%) of nanoSiC particles (2550 nm) and Al (3863 μm) were comilled for different times (16, 20, 24 h) to achieve nanocomposite powders.
