Single phase of sodium trititanate could be obtained by a hydrothermal reaction of TiO2 With NaOH aqueous solution having concentration less than 3 N under the conditions of above 400°C and above 17 MPa. The product was fibrous Na2Ti3O7 of 20-100μm in length and less than 1μm in width. Fibrous H2Ti3O7 of 10-30μm long and less than 1μm wide could be obtained by ion exchange of the fibrous Na2Ti3O7 in HCI aqueous solution.
