Abstract
The mechanochemical reaction of TiO2 and Mg via mechanical alloying of Mg, TiO2 and Al has been investigated. Reduction of TiO2 is evident from substantial formation of MgO. Weakening of Mg and TiO2 diffraction peaks along with broadening suggests refinement in grain size. Mechanically milled powder shows completion of reaction upon subsequent heat treatment while the reaction of the unmilled powder is still incomplete. Analysis suggests that the milled powder undergoes self-propagation while unmilled powder does not.
