Embodiment 1
[0012] The formula of the ceramic pigment is as follows: 50% of iron oxide, 38% of chromium oxide, 5% of manganese dioxide, 2% of mineralized powder and 5% of ammonium fluoride.
Embodiment 2
[0014] The formula of the ceramic pigment is as follows: 65% of iron oxide, 28% of chromium oxide, 3% of manganese dioxide, 3% of mineralized powder and 1% of potassium permanganate.
Embodiment 3
[0016] The formula of the ceramic pigment is: 55% of iron oxide, 33% of chromium oxide, 4% of manganese dioxide, 5% of mineralized powder and 3% of calcium nitrate.
[0017] The ceramic pigment production technology of embodiment 1-3 is:
[0018] The first step is mixing and homogenizing: the five ingredients are added into the mixer according to the ratio and mixed for 1 hour. The actual mixture without any obvious ingredients is used as the standard.
[0019] The second step is to load the bowl into the kiln: put the mixed material into the bowl (the diameter of the sagger is Φ300mm, and the depth is h100mm), put it into the kiln car according to the tunnel kiln three bowls wide and six bowls high, and push it into the kiln. Use the 1300-degree high-temperature bowl as the carrier. It is advisable to fill each bowl full, and it is better to choose a bowl with an air outlet gap. The weight of each bowl is related to the specific gravity of the material.
