抄録
The effect of pressure on the crystal structure and the lattice parameter of vacancy rich titanium monoxides has been studied using a high pressure apparatus of the tetrahedral anvil type combined with an X-ray diffraction equipment. Two kinds of specimens, TiO0.82 and TiO1.25, have been used, the former containing most of vacancies in the oxygen sublattice and the latter in the titanium sublattice. Up to the pressure of 60kbar, no significant change in the crystal structure has been observed. The change in the lattice parameter with increasing pressure is unexpectedly small for both the specimens, but a minor difference between them has been observed. An initial change is larger in TiO0.82 than in TiO1.25, while in the pressure range between 10 and 60kbar the latter shows faster decrease. The experimental results are discussed in relation to the behavior of the vacancies under high pressure.
