Abstract
Zircon-encapsulated carbon black is prepared as a black ceramic pigment by means of the sol-gel-spraying method. It is proposed that the dense zircon coating around the pigment is formed as a result of the fast transformation from sol into gel caused by the rapid extraction of solvent. To realize this, the preparation conditions are optimized as follows: the spray-drying temperature is 600 °C, the concentration of the ZrO2 sol is 0.8 mol/L, the mass ratio of the ethanol/water is 1:1, the mole ratio of the Si/Zr is 1.5 and the calcining conditions are 1250 °C with a holding time of 30 min. With these conditions, the chromatic value of the obtained pigment is L*=21.40, a*=-0.21, b*=-3.31. It is verified that the microstructure of tetragonal ZrO2 dispersed and distributed in amorphous SiO2 is necessary for the black ceramic pigment.
