Peculiarities of low temperature interaction of mechanically activated titanium hydride with nitrogen and oxygen

Abstract

The use of mechanical activation is shown to be efficient for decrease of the temperature of titanium hydride decomposition and its interaction with nitrogen. Intense milling of titanium hydride TiH1.89 results in partial loss of hydrogen and formation of TiH1.68, which in the presence of nitrogen completely transforms into titanium nitride at 500 °C. Under heating in a nitrogen atmosphere, reaction of intramolecular oxidation-reduction takes place at the expense of oxygen absorbed by mechanically activated powder with yielding lower oxide Ti2O. © 2007 Springer.
