Abstract

Low‐angle x‐ray scattering methods have been applied to determine the parameters of the scattering materials in horn keratin. A low‐angle camera of Kratky's latest design has been used for the experimental measurements. By treating the substance as a densely packed system, the evaluation of the parameters has been made after theories of Porod and Kratky. Pore analysis of the substance yields a specific inner surface of 4.7 × 10^−1^m^2^/cm^3^, a heterogeneity distance l~c~ = 290.2Å and a reduced inhomogeneity length l~r~ = 99.4Å. The volume of the pores has also been determined approximately.
