Basing on the two-parameter version of the double-flow approximation of radiation transfer theory, known as the Gurevic-Kubelka-Munk theory, absorption and scattering indexes of an elementary volume were defined for polydispersal powder of titan dioxid (anatase) in the spectral range from 2.5 to 12 mkm. For these characteristics determination, reflectivities of thick layers of the investigated powder mixtures with the support powder of the substance with the known refractive index were measured. The monodispersal powder of an oxideless glass was used as the reference. Its particles size exedeed the wavelength of radiation many times. Absorption and scattering indexes of this powder for the elementary volume were calculated by Antonov-Romanovsky formulas. The mixtures of the powders were composed in the definite concentrations. The spectral reflectivities were measured using an apparatus consisting of a IKS-31 spectrometer and an attachment with a hemispherical mirror. During the experiment it was found that the investigated characteristics of the anatase powder in the mid infrared have high spectral selectivity.
