AbstractUntil the present time, new color pigments have been developed by isotypic and homotypic mixed‐phase formation. This paper deals primarily with heterotypic mixed‐phase formation for the preparation of new colored and white pigments with the rutile structure. Dioxides and difluorides crystallizing in the rutile lattice‐form were chosen as host‐lattices for the mixed‐phase formation. Hosts of the general formula AB2can accommodate, as guests, in the form of solid solutions, oxides and/or fluorides with different structures. Characteristically, the mean statistical cation‐radius lies between 0.55 and 0.98 Å, with single radii between 0.46 and 0.98 Å. Relative quantities are so chosen that the cation to anion ratio of 1:2 prescribed by the host lattice, as well as electroneutrality,
