520 |a"A study has been made of the compositional and temperature stabilities of the high- and low-temperature modifications of titanium monoxide. The low-temperature form appears to exist as a single phase in the Ti-O system over only a narrow range of composition near TiO0.8.4. It can be formed in equilibrium with the high-temperature form by prolonged annealing; the high-temperature form has the composition TiO1.09±0.02 when the annealing is conducted at 900°C. The upper temperature limit of stability of the low-temperature form is somewhat in excess of 900°C, in agreement with earlier work. There is an indication that the high-TiO-Ti2O3 boundary should be placed at a higher oxygen content than has been given in earlier publications. Some consideration is given to the kinetic mechanism of the high-low transformation; it would appear to be diffusion-dependent"--Summary, p. 353.
