Abstract: Sn-doped ZnO particles were successfully synthesized by chemical co-precipitation method. Their morphology, phase, microstructure and infrared emissivity were characterized. The results show that the Sn-doped ZnO particles are of ellipsoid shape, their crystalline structure changed with thermal process temperature, the optimal thermal process temperature and Sn-doped proportion are 1000℃ and 15%, respectively, the minimum emissivity values are 0.42, 0.28, 0.46 and 0.48 corresponding to the infrared wavelengths of 0~∞, 3~5, 8~14 and 14~20 mm, which indicates that the Sn-doped ZnO particles have the application potential as low infrared emissivity material.
