In the manufacture of fibrous, water-insoluble alkali metal hexatitanates of the composition Me2Ti6O13, wherein Me is an alkali metal except lithium by reaction of TiO2 with an alkali metal compound which gives a basic reaction under the reaction conditions, the improvement which comprises effecting the reaction in a sulfate melt at a temperature up to about 1,300 DEG C. The sulfate melt is preferably an alkali metal sulfate. The TiO2 may be formed in situ by addition of some other titanium compound. The alkali metal compound preferably comprises sodium, potassium, rubidium or caesium and, expressed as the oxide, is present in about one-half to one-sixth the molar amount of the TiO2. |
