| Abstract: | A new compound of sodium nonatitanate, Na2Ti9O19, has been prepared by the hydrothermal reactions of titanium dioxide gel with sodium hydroxide aqueous solution. The crystal has a C-centered monoclinic lattice with the unit-cell dimensions a = 12.2, b = 3.78, c = 15.3Å, and β = 98.0°. It is expected that the structure consists of a framework different from those in tri-, hexa-, hepta-, and octatianates. |
