Title:
NANOCARBON COMPOSITE INFRARED RAY RADIATION CERAMIC
Document Type and Number:
Japanese Patent JP2021155305
Kind Code:
A
Abstract:
To provide a nanocarbon composite infrared ray radiation ceramic having high emissivity of infrared ray over a broad wavelength region, even when fine pores or voids spotted on a surface are filled or covered in order to improve water repellency or surface hardness of a surface of an infrared emitter.SOLUTION: A filling layer and/or a coating layer is formed on the a part or the entirety of a surface so as to cover the pores or voids scattered on the surface of the infrared radiation ceramics in which nanocarbon material is uniformly dispersed in the ceramic. The filling layer and/or the coating layer are mainly made of silicone or fluorine based water repellent resin. The value of the emissivity of infrared rays of 6000 to 400 cm-1 at 25°C measured by the JFCC method is 80% or larger.SELECTED DRAWING: Figure 5
