Abstract

PURPOSE: To obtain titania hydrate by extraction-removing the alkali metal component in the crystal phase of an alkali metal titanate formed by reaction at below the melting temp. of a raw material mixt. and to produce amorphous titania by dehydrating the titania hydrate at below the anatase crystallization temp.
CONSTITUTION: Anatase-type TiO2 and an alkali metal carbonate or hydroxide are mixed in a molar ratio of 6:1W1:1, and the mixt. is heat reacted at below its melting temp. to form an alkali metal titanate as crystal phase. This titanate is then dipped in water or a dil. acid soln. to extract the alkali metal component, thus being converted into titania hydrate TiO2.nH2O. The titania hydrate is heat dehydrated at below 600°C to produce amorphous titania.
