Effects of high mechanical treatment and long-term annealing on crystal structure and thermal stability of Ti(2)O(3) nanocrystals

The effect of high-energy milling and long-term annealing on the stability of Ti(2)O(3) nanocrystals was studied using a magnetic susceptibility method. In situ temperature dependences revealed that the crystal size greatly affects the magnetic susceptibility value. According to XRD, SEM and TEM dat...

Sumario:The effect of high-energy milling and long-term annealing on the stability of Ti(2)O(3) nanocrystals was studied using a magnetic susceptibility method. In situ temperature dependences revealed that the crystal size greatly affects the magnetic susceptibility value. According to XRD, SEM and TEM data, Magnéli phases Ti(9)O(10), Ti(4)O(7), Ti(7)O(19) and Ti(3)O(5) are formed.
