See full text

A method for manufacturing low effective density TiO2 includes providing a template having a surface. The template surface is coated with a titanium-containing compound that can be reduced to TiO2 at high temperature. The template is removed, thereby forming porous TiO2 particles. The effective density of the porous TiO2 particles is less than 4.
