• 論文の詳細を見る

• The infrared diffuse reflectance spectra of CaCO<SUB>3</SUB> dispersed in KBr and Si were measured over a wide concentration range. The relation between relative reflectance and concentration varies with dispersing medium. The relation follows the Kubelka-Munk (K-M) equation only in the low concentration region. The deviation in the high concentration region from the K-M equation changes with wavelength and dispersing medium. The results over the whole concentration range can be interpreted by means of a modified K-M equation in which the difference in the scattering coefficients between the sample and the dispersing medium is taken into account. The tendency of scattering coefficients of CaCO<SUB>3</SUB>, KBr, and Si calculated by the modified Kubelka-Munk equation agrees with that of refractive indexes.
