It was established that the particle size of titanium oxide β-Ti3O5 has a great influence on the processes of phase formation and the stability of particles during heating. It was shown that at a temperature of about 456 K, β-Ti3O5 micro crystals undergo a reversible first-order phase transition, in which the low- temperature β-Ti3O5 phase is transformed into the high-temperature λ- Ti3O5 phase, and at higher temperatures the β-Ti3O5 phase is partially oxidized to form the Magnéli phase Ti4O7. It was found that β-Ti3O5 nanocrystals are unstable in an argon atmosphere and at temperatures above 400 K the β-Ti3O5 powder is oxidized.
