Embodiment 1

[0030] Prepare 35 mL of 0.03 mol / L cerium chloride solution, stir and mix thoroughly, add 7.5 g of aluminum nitrate nonahydrate, completely dissolve, the molar ratio of cerium salt and aluminum salt is 1:20, dissolve 8 g of polyethylene glycol 20000 A transparent solution is formed in the mixed solution, and then 20 g of urea is added into the solution and stirred until dissolved. The mixed solution was transferred to a reaction kettle with a polytetrafluoroethylene liner and sealed. Put the reactor into an oven at a constant temperature of 120°C and keep it warm for 22 hours, then take out the reactor and let it cool down to room temperature naturally. The white product in the hydrothermal kettle was collected and washed several times with deionized water and absolute ethanol, and then dried in a vacuum oven at 60° C. for 24 hours to obtain a white powder. The above white powder was placed in a muffle furnace, calcined at 1200° C. and kept for 2 hours, and then naturally coo...

[0032] Prepare 35 mL of 0.09 mol / L cerium chloride solution, stir and mix thoroughly, add 7.5 g of aluminum nitrate nonahydrate, completely dissolve, the molar ratio of cerium salt and aluminum salt is 3:20, dissolve 6 g of polyethylene glycol 20000 A transparent solution was formed in the mixed solution, and then 19.2 g of urea was added into the solution and stirred until dissolved. The mixed solution was transferred to a reaction kettle with a polytetrafluoroethylene liner and sealed. Put the reactor into an oven at a constant temperature of 120°C and keep it warm for 26 hours, then take out the reactor and let it cool down to room temperature naturally. The white product in the hydrothermal kettle was collected and washed several times with deionized water and absolute ethanol, and then dried in a vacuum oven at 60° C. for 24 hours to obtain a white powder. The above white powder was placed in a muffle furnace, calcined at 1200° C. and kept for 2 hours, and then naturally...

Abstract

The invention discloses a cerium oxide / aluminium oxide micro-nanostructure ceramic pigment and a preparation method of the ceramic pigment. The ceramic pigment is composed of alumina fibers and cerium oxide particles according to a molar ratio of 1:20-3:10 and has uniform size and good dispersity; the lengths of the alumina fibers are 3-4mum; the sizes of the cerium oxide particles are 80-100nm; the dispersion concentration of the cerium oxide particles and the chromatic performance of the final product are controlled by adjusting the concentration of the cerium oxide; and the product is pink after being calcined for 2 hours at the temperature of 1200 DEG C. The cerium oxide / aluminium oxide micro-nanostructure ceramic pigment and the preparation method provided by the invention have the advantages of simple process, safety in operation and low cost.
