A black pigment of C/ZrSiO4 was prepared by a non-hydrolytic sol gel method with zirconium tetrachloride, tetraethyl orthosilicate and phenolic resin spheres prepared by the Stöber method as zirconium, silicon and carbon sources, respectively. The morphology, structure and residual carbon rate of the phenolic resin spheres were characterized by scanning electron microscopy, energy disperse spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy and differential thermal analysis-thermogravimetry. The effects of phenolic resin spheres amount and calcination temperature on the synthesis and color properties of C/ZrSiO4 pigments were also investigated. The results show that the obtained phenolic resin spheres are well-dispersive and the average diameter is 550 nm, and they possess oxygen-containing functional groups on their surfaces and achieve a high residual carbon rate of 48.63%. The L* value of prepared C/ZrSiO4 pigment firstly decreases and then increases with increasing the amount of phenolic resin spheres. When the amount of the phenolic resin spheres is 2% (in mass fraction) and the calcining temperature is 900 ℃, C/ZrSiO4 pigment with a good color performance (L*=39.76, a*=0.53, b*=2.21) can be obtained. Moreover, the colored glaze samples present a good color rendering performance when applying C/ZrSiO4 pigment in ceramic glaze calcined at 1 200 ℃. It is indicated that C/ZrSiO4 pigment could have a promising application in coating, ceramic and glass decoration.
