Phase Analysis Studies on the Titanium-Oxygen System.

The titanium--oxygen system has been studied by means of x-ray powder photographs of preparations quenched after annealing at various temperatures. A number of phases not previously described has been observed, viz., Ti/sub 2/O, TiO (low-temperature modification), Ti/sub 4/O/sub 7/, Ti/sub 5/O/su b 9/, Ti/sub 6/O/sub 11/, Ti/sub 7/O/sub 13/, Ti/sub 8/O/sub 15/, Ti/sub 9/O/sub 17/, and Ti/ sub 10/O/sub 19/. The extensions of the homogeneity ranges have been determined for the phases with variable composition. (auth)
