TITANIUM-CONTAINING PEARLESCENT PIGMENTS |
摘要 |
<p>Single or multi-coat titanium-containing nacreous pigments consisting of iron titanate and possibly titanium and/or iron oxide, obtainable by solidifying an aqueous solution of a thermally hydrolysable titanium compound on an endless belt, removing the layer formed, coating the titanium dioxide platelets after or without intermediate drying in the wet process with iron oxide, drying and calcining the material obtained in an oxidising or reducing gas atmosphere at at least 500 ~C, in which the thicknesses of the titanium dioxide and iron oxide layers are adjusted in such a way that either the stoichiometric ratio between iron oxide and titanium dioxide needed for pseudo-brookite or ilmenite formation is obtained or there in an excess of iron oxide or titanium dioxide.</p> |
