Abstract
A method of making fibrous alkali titanates comprising the steps of preparing a mixture including a titanium compound and an alkali metal compound in a molar ratio of 1.0 to 8.0 in terms of TiO.sub.2 :M.sub.2 O (M: Na, K, Rb, Cs), heating said mixture at a temperature of 1200.degree. to 1600.degree. C to the molten (liquid) phase, cooling the thus heated mixture to room temperature , and washing the thus treated product. This method is advantageous because fibrous alkali titanates of large ratio of length to diameter can be easily produced in high yield.
