Polycrystalline black ceramics for infrared heating were prepared. These ceramics have excellent properties such as antierosion, high thermal shock resistance and high abrasive resistance to high temperature gas jet. The normal total emissivity and refractoriness are more than 0.9 and 1790℃, respectively. The ceramics have been employed to manufacture lamps, tubes and plate heating elements, as well as coatings for use on the surface of furnace. The results of these applications indicated that these black ceramics can save energy in industries heating.
