Abstract

The crystallization behavior of titanium dioxide, produced by a sol-gel method, and its dependence on synthesis conditions has been investigated. It was found that the anatase phase of titanium dioxide can be formed at temperatures as low as 95°C in the presence of water, but the material produced at this temperature shows poor crystallinity. It is difficult to convert this poorly crystalline materials to a more highly crystalline structure upon application of a heat treatment at higher temperatures. A product with much better crystallinity was obtained when amorphous titania, processed only at ambient temperature, was subjected to heat treatment at 450°C.
