Embodiment 1
[0022] A kind of red ceramic pigment, the parts by weight of each component are:
[0023] 0.35 parts of ferric oxide, 3 parts of chromium nitrate, 3 parts of aluminum nitrate, 0.5 parts of silicon dioxide, 5 parts of zinc oxide, 25 parts of urea, 0.1 part of sodium fluoride, and 15 parts of sodium fluorosilicate.
[0024] Its preparation method comprises the following steps:
[0025] Mix and stir the raw materials evenly to obtain a uniform mixture, then grind it thoroughly for 2.5 hours; calcinate the mixture at 700°C for 5 hours; after calcining, add the powder into purified water 20 times its weight, stir for 30 minutes, and filter out Moisture, drying; the dried solid is ground by a ball mill and passed through a 300-mesh sieve to obtain a red ceramic colorant.
Embodiment 2
[0027] A kind of red ceramic pigment, the parts by weight of each component are:
[0028] 0.45 parts of ferric oxide, 5 parts of chromium nitrate, 5 parts of aluminum nitrate, 0.75 parts of silicon dioxide, 7.5 parts of zinc oxide, 30 parts of urea, 0.25 parts of sodium fluoride, and 17.5 parts of sodium fluorosilicate.
[0029] Its preparation method comprises the following steps:
[0030] Mix and stir the raw materials evenly to obtain a uniform mixture, then grind it thoroughly for 2.5 hours; calcinate the mixture at 700°C for 5 hours; after calcining, add the powder into purified water 20 times its weight, stir for 30 minutes, and filter out Moisture, drying; the dried solid is ground by a ball mill and passed through a 300-mesh sieve to obtain a red ceramic colorant.
Embodiment 3
[0032] A kind of red ceramic pigment, the parts by weight of each component are:
[0033] 0.1 part of ferric oxide, 1 part of chromium nitrate, 5 parts of aluminum nitrate, 0.5 part of silicon dioxide, 10 parts of zinc oxide, 35 parts of urea, 0.1 part of sodium fluoride, 20 parts of sodium fluorosilicate.
[0034] Its preparation method comprises the following steps:
[0035] Mix and stir the raw materials evenly to obtain a uniform mixture, then grind the mixture thoroughly for 2.75 hours; calcinate the mixture at 725°C for 5.5 hours; after calcining, add the powder into pure water that is 22.5 times its weight, stir for 45 minutes, and then filter Remove water and dry; grind the dried solid with a ball mill and pass through a 325-mesh sieve to obtain a red ceramic colorant.
