Description

Anodic oxidation of titanium metals in nitric acid was subjected to ultrasonic vibration. Products were found to be titanium dioxide particles with poor crystallinity. Light brown color of the product suggested that nitrogen from nitric group could be dissolved in the lattice. Application of a 28kHz ultrasound resulted in highly aligned pore with 30nm diameter at the nitric acid concentration of 1mol/L; while no porous structure was observed without sonication at the same concentration. Crystalline phase after calcined at 400℃ was rutile for the non-sonicated but anatase for the sonicated specimen. Ultrasonication during the anodic oxidation suppressed formation of the rutile microcrystals.
