Physical Properties of Non-Stoichiometric Sintered TiO Ceramics

Non-stoichiometric sintered TiO ceramics were produced by sintering at 1350℃ in a vacuum of 10^ Torr, starting from the mixed Powder of titanium oxide and titanium as raw materials. The TiO phase obtained was mainly cubic, but it contained complex ordered lattice structure phase only a little in the como position range between TiO_ and TiOi_. Some physical properties, such as mechanical, electrical and optical properties, and some factors governing the microstructure of the sintered bodies, such as mean crystal size, lattice strain and apparent density, were measured and related with the composition of non-stoichiometric TiO phase
