Abstract: Beige-brown encapsulated pigments are obtained by means of the encapsulation of iron titanates of the formula Fe2TiO5 in zirconium silicate crystals. The production takes place by calcining a mixture of zirconium oxide with a particle size distribution of /=4 m2/g, silicon dioxide and iron oxides and titanium oxides or oxide-forming Fe compounds and Ti compounds in the presence of mineralizers under oxidizing conditions at 800 DEG to 1300 DEG C.

Abstract: Grey-black inclusion pigments are obtained by enclosing iron titanates of the formula FeTiO3 in zirconium silicate crystals. They are prepared by igniting a mixture of zirconium oxide having a particle size distribution of 6 to 10 mu m and a specific surface area of 2 to 5.2 m /g, silica and iron oxides and titanium oxides or iron compounds and titanium compounds forming oxides in the presence of mineralisers under oxidising conditions at 800 to 1300 DEG C.
