| titleOfInvention | Magnetite particle powder for black pigment and method for producing the same |
| abstract | (57) [Abstract] [Problem] The black pigment and the coloring power as a black pigment are large. Further, the present invention provides a magnetite particle powder for a black pigment which is excellent in heat resistance, compatibility with various kinds of mixing agents and dispersibility. SOLUTION: (1) An aqueous solution of ferrous salt is added to an aqueous solution of alkali hydroxide and mixed in a molar ratio (alkali hydroxide / ferrous salt solution) of 1.28 to 2.78. 8 in liquid An oxidizing gas is passed at 0 to 100 ° C. and an aluminum compound is added within a range of 3 to 4 hours. (3) Thereafter, the oxidizing gas is continuously passed to generate magnetite particles, followed by filtration. By performing washing, drying and pulverization, the average particle diameter is 0.1 to 0.2 μm, and the specific surface area is 18 to 50. m 2 / g, the geometric standard deviation is 1.30 or less, and the aluminum compound is 1.5 to 10.0 wt% with respect to Fe in terms of Al. The contained magnetite particle powder for black pigment is obtained. |
