N2 - Using SiO 2, Fe 2O 3, Cr 2O 3 and MnO 2 powders as raw materials, the high temperature infrared emissivity energy-saving coatings were prepared by combined solid-state and milling method. The physical and chemical properties and microstructures of the obtained coatings were characterized by X-ray diffraction (XRD), hemisphere-point test, infrared radiation meter and nano-particle size meter. And their thermal shock resistance was also investigated by wind quenching-cracks determination method. The results showed that the prepared SiO 2-Fe 2O 3 -Cr 2O 3-MnO 2 coating systems exhibited a infrared emissivity of 0.93 in the band of 1-22 μm and good thermal shock resistance, and their operating temperature cauld be up to 1400°C. Besides, when the prepared coatings were applied in gas shuttle drying kiln, the energy consumption of the kiln decreased by 15%. It can be expected that after one year of use, their infrared emissivity remains up to 0.90, which indicates that the coatings have excellent anti-aging performance.
