２１８４４号公報などにその具体例も開示されている。If an object has a temperature above absolute 0 degrees, there is always thermal radiation, and the spectral characteristics of this thermal radiation are determined by the object's temperature and spectral emissivity.It is possible to heat an object that has a high emissivity in the infrared region to an appropriate temperature. It has been confirmed through experiments that infrared radiation can be obtained by doing so. This type of electromagnetic wave, infrared rays, is usually divided into near infrared rays and far infrared rays.
The boundary is generally 5 microns. Furthermore, when this infrared ray is absorbed by a material, almost all of it is converted into thermal energy, but ceramics in particular have the property of emitting infrared rays with relatively long wavelengths, although this varies depending on the material. In general, materials with high infrared radiation characteristics are considered to be zirconia, alumina, and titania, and are disclosed in Japanese Patent Publication No. 53-44928, Japanese Patent Publication No. 11809-1980, Japanese Patent Publication No. 2421-1987, Special Publication No. 47-25010 and Special Publication No. 54-
Specific examples thereof are also disclosed in JP-A No. 21844 and the like.

料として満足できるものは少なかった。However, when we look at the characteristics of these ceramics as radiation media, they have advantages and disadvantages, such as high radiation in the low wavelength region, that is, near-infrared radiation, and low far-infrared radiation in the long wavelength region, which is most needed for heating. However, there have been few satisfactory practical infrared emitting materials.
