Abstract: The suspension of zirconium hydroxide and cadmium sulfide selenide prepared by co -precipitation method was coated by nano-sized SiO 2 sol prepared by hydrolysis of tetraethyl orthosilicate . The precursor was rapidly calcined to synthesize zircon-cadmium sulfide selenide inclusion pigment at high temperature.The pigments were characterized by XRD, SEM, laser particle size analyzer, chromaticity meter and so on .The effects of calcination temperature and the ratio of Zr/Cd on the diameter and chromaticity of pigment were studied with a fixed ratio of Zr /Si.The results show that with a mole ratio of Cd:S:Se=4:3:1 , Zr:Cd=3:1 , Zr:Si=1:1 and LiF as the mineralizer , the a* value corresponding to the red chromaticity of this pigment is 32.04 and D50 is in the vicinity 2μm while being calcined at 1050 ℃for 30 min.The hydrolysis-coprecipitation method provides a possible access for the application of zircon-cadmium sulfide selenide inclusion pigment in ceramic ink-jet printing .
