The mineral pigments modified a base of tio2 and their method of preparation

摘要

P the present invention relates to the colored pigments based on titanium compounds, characterized in that they consist of crystalline phases of the rutile tio2, perovskite catio3 and trigonal cotio3, and they contain from 2 to 12% by weight of cobalt and 4 to 20% by weight of calcium, with respect to the total amount of tio2, and in that they have a dominant wavelength λ d of between 530 and 560 m mu. / p
