Abstract: In this paper , The influence of chrome- tin pink pigment synthesized are mainly researched by sol- gel method with citric acid. In virtue of scan electron microscope (SEM) and (BET), it was confirmed that the mole ratio of C/Mn+ (citric acidvs . metal ion ) was 1: 2, and the volume ratio of TEOS/EtOH/H2O was 1:6:2 , stirring at the temperature of 70℃ for 30 minutes . Via the TG- DSC and the infrared (IR) spectroscopy on the dried gel of pigment precursors , metalion in the macromolecule network s tructure formed by the citric acid dis tributed more uniformly,. And the synthes izing temperature with the citric acid moved up 50℃.
