Influence of graphite addition on the reactivity of Ti powder with H2 under ball milling.

The effect of graphite addition on the mechanism of hydrogen uptake by titanium during mechanochemical activation in hydrogen flow was studied using kinetic, structural, microscopic, and spectroscopic techniques. As was found, already a small graphite admixture of about 0.5 wt % changed the kinetics of mechanically induced H2 sorption and significantly stimulated Ti-H2 interaction. Two new types of occupation sites available for hydrogen were observed, which are characterized by low H2 desorption temperatures: about 650 and 750 K instead of 1000 K.

Stimulating effect of graphite admixture on hydrogen sorption-desorption properties of mechanically activated titanium powder.

The effect of graphite admixture on hydrogen sorption-desorption properties of mechanically activated electron microscopy, temperature-programmed reaction, and temperature-programmed desorption techniques. The major effect of graphite addition was found to be the formation of microporous carbon matrix particles containing randomly distributed titanium particles only several nanometers in diameter. This powder architecture enhances hydrogen transport to the titanium surface without hindrances and promotes titanium-hydrogen interaction by modifying the titanium surface and subsurface layers with interstitial carbon atoms.

[Preparation of exact solutions of acids and bases].

The procedure for the preparation of the necessary volumes of acid and base solutions in certain concentrations is described in brief, as is the determination of mass concentrations of the original acids and bases with the use of quantitative titrometric analysis. Mathematical formulae necessary for this work are presented.
