| titleOfInvention | Method for producing cobalt black pigment |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a black pigment which removes redness and yellowishness from a conventional black pigment made of cobalt trioxide powder and exhibits a slight green or blueness. SOLUTION: Cobalt oxide fine particles are surface-treated with an aluminum compound, and then the surface-treated fine particles are fired in an oxygen-containing atmosphere, and have a Co 3 O 4 crystal structure and contain aluminum. Cobalt black pigment consisting of fine particles The cobalt oxide preferably has a CoO and Co 3 O 4 crystal structure produced by a direct current arc plasma method using a consumption anode electrode made of cobalt or a cobalt compound. |
