Ambient-Temperature Mechanochemical Formation of Titanium Nitride-Alumina Composites from TiO2 and FeTiO3
Welham, N; Kerr, T
The fabrication of a homogeneous submicrometer-sized powder composed of nanocrystalline (<10 nm) alumina and titanium nitride during high-energy ball-milling is reported in this paper. The starting materials were rutile (TiO2) and aluminum powder. A similar composite with iron was also produced using the mineral ilmenite (FeTiO3) as the starting material. The powders were ball-milled together under a nitrogen atmosphere for 100 h in a laboratory-scale mill and subjected to thermal analysis and...[Show more]
