Röntgen-Beugungsuntersuchungen an Bi-In-Schmelzen / X-Ray Diffraction Experiments with Bi-In-melts

Using MoK α-radiation and a θ-θ diffractometer from molten In and Bi as well as six molten Bi-In alloys (8; 22; 27; 33.3; 50; and 77 at % Bi) intensity curves were obtained at 10 °C above the liquidus temperature. The measurements were performed in the q-region up to 14.5 Å^-1. From the Fourier transform of the structure factors coordination numbers N^I_tot and radii r^I_tot were obtained. The concentration dependency of N^I_tot and r^I_tot leads to the conclusion, that the Bi-In melts belong to the compound forming melts.
