| titleOfInvention | Submicron cobalt-containing black ceramic pigment and preparation method and application thereof |
| abstract | The invention belongs to the field of ceramic pigments, and discloses a submicron cobalt-containing black ceramic pigment and a preparation method thereof. The method comprises the steps of taking at least one of nitrate, oxide and hydroxide of an element A and at least one of nitrate, oxide and hydroxide of an element B as raw materials, wherein A is Co + Ni + Cu + Mn, and B is Fe + Cr, preparing a nitrate aqueous solution, adding citric acid, glycine and urea, stirring and heating to prepare a gel, drying and crushing the gel, adding NaCl, performing ball milling and mixing, calcining, washing with water, drying and performing jet milling to prepare the cobalt black pigment for the ceramic ink, which has a spinel structure, good crystal grain development and a grain size of 0.1-1.0 mu m. Compared with the cobalt black synthesized by a solid phase method in the market, the submicron cobalt black can be applied to ceramic ink-jet ink without secondary grinding, so that the hue change of pigments caused by over grinding is prevented, the production process of the ink can be simplified, and the production cost of the ink can be reduced. |
