Microwave hydrothermal synthesis of nanocrystalline rutile

Titanium dioxide of the rutile phase has been synthesized using titanium tetrachloride and hydrochloric acid by means of microwave hydrothermal method. The mixture solution is processed in microwave hydrothermal autoclave first at 120 degrees C for 1.5 h and then at 180 degrees C for 1 h to precipitate rutile powders. it was revealed that well-dispersed and shuttle-like rutile TiO2 with the average diameter of 10 nm was formed by means of XRD and TEM.
