Abstract

The invention discloses black inorganic ceramic pigment with a perovskite structure and a preparation method thereof. The inorganic ceramic pigment has a structure of YMn1-xEuxO3, wherein X is greaterthan or equal to 0.00 and less than or equal to 0.15. The preparation method disclosed by the invention comprises the following steps: (1) dissolving corresponding yttrium nitrate, manganese nitrateand europium nitrate into distilled water respectively to obtain a mixed solution; (2) adding the mixed solution into a water solution of glycine; (3) after magnetically stirring, combusting and concentrating by utilizing a combustion kettle to obtain precursor powder; (4) calcining the precursor powder; to obtain the black inorganic ceramic pigment with the perovskite structure. The preparation method disclosed by the invention has the advantages that energy and time are saved and raw materials are easy to obtain; an obtained product has good ion dispersity and uniform particle size distribution, and has no toxin and no radioactivity; the preparation method has low synthesis temperature and a simple and controllable technology, and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of ceramic pigments, and in particular relates to a perovskite-structured black inorganic ceramic pigment and a preparation method thereof. Background technique [0002] Black is basically defined as the absence of any visible light entering the visual range, as opposed to white, where all light within the visible spectrum enters the visual range at the same time. If the pigment absorbs all visible light in the spectrum and does not reflect light of any color, the human eye perceives it as black. If the pigments of the three primary colors are mixed in an appropriate proportion to minimize the reflected color light, the human eye will also perceive it as black. So blackness can be caused either by lack of light (dark night) or by absorption of all colored light (black pupils). For a long time, black ceramic products have been loved by people for their dignified, stable and solemn color sense. The "Longsha...
