Abstract

High quality, hexagonal prismatic Na 2Ti 6O 13 whiskers were easily grown by the slow-cooling of a NaCl flux. Whisker growth was conducted by heating a mixture of solute (Na 2CO 3 + TiO 2) and flux (NaCl) at 1100°C and held at this temperature for 10 h, and then the mixture was cooled at a rate of 5°Ch -1 to 500°C. The Na 2Ti 6O 13 whiskers had average lengths of up to 100 μm and widths of up to 2.0 μm and were transparent and colorless. The whiskers were hexagonal prisms bounded by well-developed {010}, {100}, {001}, and {201} faces. The whiskers exhibited good photocatalytic activity under UV light irradiation. Sodium chloride was found to be a very suitable flux for environmental friendly growth of photocatalytic whiskers.
