| Abstract: | The infrared radiant ceramic materials were prepared by calcination at high temperature. Based on the study of infrared radiant emissivity and X — ray diffraction spectra, the results indicate that spinel structure possesses the higher infrared radiant emissivity. The reason of the higher infrared emissivity of the spinel structure has been explained according to the Group Theory. |
