以Fe 2 O 3、MnO 2、CuO、Co 2 O 3等过渡金属氧化物经高温固相反应制备了尖晶石结构的红外辐射粉料，然后按等质量比加入硅酸盐粘接剂制备了红外辐射节能涂料，用XRD、红外辐射测量仪和热膨胀仪等对红外辐射陶瓷粉料的微观结构和性能进行了表征，采用热震法和烧水对比试验对红外辐射涂料的耐热震稳定性和节能效果进行了研究。结果表明，经1080~1150℃高温焙烧制备的尖晶石结构的红外辐射粉料在8~14μm波段的辐射率均在0.89以上，涂层具有良好的附着力和耐热震稳定性。烧水模拟试验表明，涂覆红外辐射节能涂料后不锈钢容器的吸热和热交换能力明显增加，能耗可降低28%左右。

A novel infrared radiant material with spinel structure was developed using MnO2, Fe2O3, CuO and Co2O3 powders as raw materials by high temperature solid-state reaction method. The infrared radiant coating was fabricated by doping silicate adhesive into the infrared radiant ceramic powders at the same ratio. The microstructures and properties of the obtained infrared radiant powders were characterized by X-ray diffraction (XRD), infrared radiation meter and thermal expansion meter. Their thermal shock resistance was also investigated by wind quenching-cracks determination method and the energy saving effect was evaluated by boiling water simultaneous test, respectively. The results show that,the prepared infrared radiant powder at 1080~1150℃ exhibits an infrared emissivity more than 0.89 in the band of 8~14 μm. The infrared radiant coating has an excellent adhesion and thermal shock resistance. Besides, the simulate test shows that when the prepared coating was applied on the surface of stainless steel bowl could significantly increase the endothermic and heat exchange capacity. The energy consumption decrease about 28% by calculated.
