Problems solved by technology

Either affected by the atmosphere (such as FeO·Fe 2 o 3 ), or it is affected by the composition of the glaze, or the price is very expensive, etc.
[0003] The stability of pigments has always been a problem in ceramic production, especially high-temperature (1300°C) pigments. At present, only cadmium selenium red (yellow) pigments wrapped in zirconium silicate are high-temperature stable pigments, while other color packages The development and application of colorants has not been reported yet

Abstract

The invention discloses a method for preparing a black pigment by wrapping carbon black with zirconium silicate. The black pigment with high wrapping rate is synthesized at the temperature of 1000-1100 DEG C by using high pigment carbon black or high wear-resistant carbon black or acetylene carbon black as raw materials and using a non-hydrolytic sol-gel technology. The synthesis method is simple in process, high in synthesis speed and low in synthesis temperature; and the prepared black pigment is pure in color, stable in performance, high in service temperature being up to 1300 DEG C, capable of being widely applied to high-temperature glaze materials of various ceramic products and higher in economic values.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a method for preparing black pigment by wrapping carbon black with zirconium silicate. Background technique [0002] The removal of (Cr, Fe) from black pigments currently used in ceramic production 2 o 3 Except corundum type, others are spinel type pigments, such as FeO·Fe 2 o 3 , Co-Cr-Fe, Co-Mn-Fe, Co-Mn-Cr-Fe, Co-Ni-Cr-Fe, Co-Mn-Ni-Cr-Fe, Co-Mn-Al-Cr-Fe, Co -Ni-Cr-Fe-Si etc. Although the spinel pigment has a stable structure, high temperature resistance, low sensitivity to the atmosphere and good chemical stability, these pigments only have the best color in the lime glaze, and the lime glaze is required to be zinc-free and non-flammable. Magnesium, or low zinc, low magnesium. These pigments are unstable in calcium-magnesium glazes, and in most cases, more stable spinels are formed, making them gray or gray-green; while in calcium-zi...
