| 中文摘要 | Novel Co0.3Cr0.7Ox (x=2-3) particles with spinel structure were synthesized via precipitation method through the reactions among CoSO4, Cr(NO3)(3) and NaOH solutions, followed by spray-drying and sintering at 1200 degrees C for 4h in the air. The particles were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results revealed that the particles are composed of Co0.3Cr0.7Ox phase without the presence of other phases. The SEM observation showed that the particles are in the shape of sphere with well flowability. Infrared radiation test indicated that the total infrared normal emissivity of the coating made of Co0.3Cr0.7Ox can be up to 0.92 at 800 degrees C. And the normal emissivities of the prepared Co0.3Cr0.7Ox particles are always slightly larger than those of CoCr2O4 particles prepared by solid-state reaction method in the test temperature range of 50-300 degrees C. The relatively high thermal emissivity of Co0.3Cr0.7Ox is assumed to be mainly attributed to the spinel structure. These results indicated that Co0.3Cr0.7Ox particles are a good thermal radiation material, which can be used as infrared radiation layer in thermal protection system. |
