Titanate nanofibers were synthesized by hydrothermal
method (120°C for 72 h) using low-cost ilmenite mineral as the
starting material. After hydrothermal method, quantity of TiO2
increased due to decreasing of impurities content. The
prepared nanofibers showed the length of 2-7 μm and formed
some bundles of 6-100 nm in diameter. The operation of this
synthesis method is a simple hydrothermal method using Thai
autoclave unit.
