| contents | Emissivity measurement of high-emissivity black paint at CENAM D. Cárdenas-García Física, Astronomía y Matemáticas Spectral emissivity radiation thermometry To measure the temperature of the surface of an opaque object by radiation thermometry, it is necessary to know its surface emissivity. High-emissivity black paint can be applied to the inner walls of a cavity to be used as a blackbody radiator. It can also be applied to some highly reflecting metals so that their temperature can be estimated by radiation thermometry. In this work, it is described the emissivity measurement of high-emissivity black paint that has been used for the two applications described above. The average emissivity of the measured paint in the 8 to 14 micrometers wavelength range was estimated as 0.972 ± 0.012. The results obtained may be of use for those using the paint at temperatures from 50 to 150◦ C. 2014 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57031049007 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
