Abstract
The milling of titanium hydride in a planetary mill is shown to increase the
specific surface area of powder, to decrease the hydrogen content in it, and
to intensify chemical activity. This makes it possible to obtain titanium
nitride from the titanium hydride in a nitrogen atmosphere at as low
temperature as 500 °C. Due to the presence of oxygen adsorbed by a
mechanically activated powder under heating in a nitrogen atmosphere,
the reaction of intramolecular oxidation-reduction of titanium
takes place. As a result, the lower oxide Ti2O is formed.
