The aim of this work is to produce white pigments having less amount of Ti 4+ than that of pure TiO 2 . It develops synthetic methods for the preparation of nanosized white pigments based on alkaline earth metal titanates and potassium titanium oxophosphate with a high surface area (30–80 m 2 /g) from ilmenite. The preparative methods involve the extraction of titanium as a water‐soluble titanium oxychloride from ilmenite and coprecipitation of constituent ions of pigments from their aqueous mixture solutions using a suitable precipitant. All the synthesized pigments have been characterized by X‐ray powder diffraction, transmission electron micrscope, and ultraviolet–visible spectroscopy study, energy‐dispersive X‐ray analysis, and Brunauer–Emmett–Teller surface area measurement.
