Embodiment 1

[0041]3.83g of yttrium nitrate, 2.87g of manganese nitrate and 1.49g of potassium chloride were dissolved in 100ml of water and stirred to obtain solution 1. Dissolve 3.01g of glycine into 50ml of water to obtain solution 2, pour solution 1 into solution 2, stir at 60°C until clear solution 3, stir at a speed of 80 rpm for 2 hours with ultrasonic oscillation, and then stir at 120°C Concentrate and burn under high pressure to generate a loose powder that is the precursor. Pour the powder into the pigment coating agent and soak for 1 hour, then filter the soaked precursor powder and air-dry it, and then calcinate the air-dried precursor powder at 900°C 4 hours, grind again to get the final sample YMnO 3 .

Embodiment 2

[0043] 3.83g of yttrium nitrate, 2.73g of manganese nitrate, 0.21g of ferric nitrate and 1.49g of potassium chloride were dissolved in 100ml of water and stirred to obtain solution 1. Dissolve 3.01g of glycine into 50ml of water to obtain solution 2, pour solution 1 into solution 2, stir at 60°C until clear solution 3, stir at a speed of 90 rpm for 2 hours with ultrasonic oscillation, and then stir at 120°C Concentrate and burn under high pressure to generate a loose powder that is the precursor. Pour the powder into the pigment coating agent and soak for 1 hour, then filter the soaked precursor powder and air-dry it, and then calcinate the air-dried precursor powder at 900°C After 4 hours, grind again to get the final sample YMn 0.95 Fe 0.05 o 3 .

Embodiment 3

[0045] 3.83g of yttrium nitrate, 2.59g of manganese nitrate, 0.41g of ferric nitrate and 1.49g of potassium chloride were dissolved in 100ml of water and stirred to obtain solution 1. Dissolve 3.01g of glycine into 50ml of water to obtain solution 2, pour solution 1 into solution 2, stir at 60°C until clear solution 3, stir at a speed of 100 rpm for 2 hours with ultrasonic oscillation, and then stir at 120°C Concentrate and burn under low temperature, pour the powder into the pigment coating agent and soak for 1 hour, then filter the soaked precursor powder and air-dry it, and calcinate the air-dried precursor powder at 900°C for 4 hours, and grind it again to get the final product. Sample YMn 0.9 Fe 0.1 o 3 .

Abstract

The invention discloses a preparation method of a black inorganic ceramic pigment, the black ceramic pigment has YMn 1‑x Fe x o 3 structure, wherein: 0.05≤x≤0.30; the preparation method of black ceramic pigment comprises the following steps: (1) according to the molar ratio of Y, Mn and Fe, get corresponding yttrium nitrate, manganese nitrate, ferric nitrate respectively and be dissolved in distilled water Obtain a mixed solution; (2) add the mixed solution to an aqueous solution of glycine; (3) use a magnetic stirrer to stir for more than 1 hour at 60° C., and burn and concentrate at 100 to 120° C. to obtain a precursor powder; (4) use Calcining in a muffle furnace, the calcination temperature is 650-900° C., and the calcination time is 2-4 hours to obtain a black ceramic pigment with a perovskite structure; the preparation method of the present invention is simple, the raw materials are easy to obtain, and the obtained product particles have good dispersibility. The particle size distribution is uniform, the synthesis temperature is low, the process is simple and controllable, and it is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of ceramic pigments, in particular to a preparation method of black inorganic ceramic pigments. Background technique [0002] Conventionally, with regard to black pigments, blue is more preferable than red in terms of hue, and in recent years, the market demand for pigments capable of achieving clearer hues has been increasing in a wide range of fields. Black pigments with blue hues are in strong demand. [0003] At present, after more than ten years of rapid development in my country's architectural sanitary ceramics, it has become the largest and most important production base of architectural sanitary ceramics in the world. The ceramic inkjet production technology developed in recent years has been booming in my country. Ceramic inkjet technology At the same time, great progress and application have been made in the field of architectural ceramics production. The direct application of inkjet printing equi...
