TiO nanopowder was synthesized from commercial TiO micron-sized powder by low-energy wet ball-milling. As a result of annealing, cubic TiO is a dominant phase compared with the polymorph structure of raw TiO. Moreover, milled TiO shows good dispersibility, indicating a potential raw material for solution-based production.
