Abstract： By testing the infrared radiation ceramic material (ZrO₂-Clay-Fe₂O₃, MgO-Al₂O₃-SiO₂ and Al₂O₃-Clay )and infrared absorbable property of several kinds of ceramic substance, it is found that the three kinds of infrared radiation Ceramic materials have high specific emissivity, and that each of the several kinds of ceramic substance has two high absorbable bands in far-infrated band, which is in accord with the principle of the matching absorbility" the feasibility is analyzed about applying infrared radiation ceramic materials to drying source for ceramic substance.

Keywords:  dry, infrared radiation ceramic.
