ABSTRACT:
A process for preparing high quality titanium dioxide which exhibits excellent reflectance and tint strength when incorporated into a coating formulation. The process involves the preparation of a seed solution wherein one of the seed curing factors of time, temperature and amount of alkaline neutralizing agent are varied to establish maximum reflectance and tint strength values obtained by the final product. The process can be repeated to analyze one or both of the other factors. The process can be used to prepare titanium dioxide in the anatase or rutile form and on a batch or continuous basis.
