Abstract
Hugoniot data were obtained for titanium monoxide TiO x ( x =0.84, 1.06, and 1.28), up to about 600 kbar by shock wave compression. A small explosive lens system was used for the purpose of generating plane shock waves. Shock velocities and free surface velocities were measured by means of an electric pin-contactor method; the shock state was computed on the basis of free surface approximation. Regardless of the values of x , the compounds TiO x were shown to be extremely incompressible even in this ultrahigh pressure region; no evidence was found for significant filling of vacancies.
