ABSTRACT:
A dilution material for measuring infrared spectra comprising two or more kinds of the inorganic materials capable of transmitting infrared rays, of which the surface reflection loss is less than one third, and at least one of which the refractive index is different from another one by more than 0.1, and other means capable of improving infrared spectra of highly scattering samples such as coal powder and pitch powder.
