Abstract
Titanium subhydride is produced in a reactor by heating a selected amount of finely divided titanium compound at a selected temperature for a selected period of time under dynamic vacuum conditions. Hydrogen is removed substantially uniformly from each powder grain and there is produced a subhydride of substantially uniform titanium-hydrogen composition. Selection of the amount, temperature and time produces a subhydride of selected titanium-hydrogen composition.

A process for reproducibly preparing a titanium subhydride of the formula TiH.sub.x having a substantially uniform titanium-hydrogen composition, from an original titanium-hydrogen composition of the formula TiH.sub.y, wherein x<y.ltoreq.2, said process comprising the steps of:
- (a) in a reactor, heating a quantity of finely powdered TiH.sub.y at a selected temperature in the range of about 375.degree. to 475.degree. C. for a selected period of time of from about 1 to 24 hours, under dynamic vacuum conditions that constantly allow removal of hydrogen from said reactor, whereby hydrogen is removed substantially uniformly from each original powder grain of TiH.sub.y to produce the TiH.sub.x subhydride, and
- (b) recovering said TiH.sub.x subhydride.
