Abstract: The Pr－yellow and Nd－purple zircon pigment powders were successfully prepared by the sol－gel method．The obstained pigment with different minerilizer synthesised at different temperature was tested by XRDXPSspectral reflectance and grain distributionand it is considered that the color of the pigment is better and the grain distribution is narrower than that by the coprecipitation method．
