ABSTRACT:
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.
