摘要:
A method for separating sodium and potassium from an aqueous solution containing such metals, which comprises selectively ion-exchanging sodium and potassium with titania hydrate (TiO.sub.2 .multidot.nH.sub.2 O where n=1 to 2) obtained by treating potassium titanate to remove potassium therefrom, followed by a reaction at a temperature of from 25.degree. to 80.degree. C. to desorb and purify sodium and potassium.
摘要:
The present invention relates to fine hollow powder with a titanium oxide shell, obtained by spray drying an exfoliated titania sol, and thin flaky titanium oxide powder obtained by pulverizing the fine hollow powder, and also to processes for producing the same. The present fine hollow powder and thin flaky titanium oxide powder have a distinguished dispersibility and are useful for additives to cosmetics, pigments, paints, etc., and the present fine hollow powder also has a distinguished flowability and is useful for seed particles for flow measurement.
