Al0.97Y0.03PO4 thermal radiation material was prepared by homogeneous precipitation method. The influences of Y-doping on crystallization behavior, infrared vibration absorption, surface chemical elemental composition, chemical environment, grain size and infrared emissivity property were analysed in detail by X-ray diffraction, X-ray photoelectron spectroscopy, Solid state NMR, Scanning electron micrograph and infrared emissivity spectrometer, respectively. It is found that the doping of Y greatly improves the infrared radiation property and reduces the grain size. Compared with non-doped AlPO4, Al0.97Y0.03PO4 thermal radiation material possesses a higher infrared emissivity of 0.931 +/- 0.002, which suggests that it will have a promising application in the field of infrared heating and drying.
