ABSTRACT:
A heat-resistant inorganic pigment of the present invention comprises a composite metal oxide containing Ti and two divalent metals selected from the group consisting of Mg, Fe, Ni and Co, the content of said two divalent metals in said composite metal oxide being 0.95 to 1.05, in an atomic ratio, based on Ti, and the composition ratio of said two divalent metals being 95/5 to 5/95 in an atomic ratio. The pigment of the present invention is useful as a pigment for a heat-resistant coating material and is a novel heat-resistant inorganic pigment which does not pollute the environment.
