    The hydrothermal oxidation of titanium metal powder was performed in concentrated potassium hydroxide solutions above 150 °C. K2Ti2O5, K4Ti3O8 and a new compound KTiO2(OH) were formed as single phase and fibrous amorphous products which transformed to K2Ti4O9 and K2Ti6O13 and K2Ti2O5 by calcination were also obtained depending on the reaction conditions. A formation diagram of products in the Ti-KOH-H2O system has been constructed at the region of KOH concentration from 0 to 90 mol·kg-1-H2O and the temperature from 150 to 350 °C.
