Abstract X-ray diffraction was done with molten Ni81 P19 (930°C) and with molten Ni68.8 P31.2 (1160°C). The second peak of the structure factor and the pair correlation function of the Ni81P19 -melt shows a shoulder, as was observed for amorphous Ni80P20 . The first two peaks in the pair correlation function can be modelled using crystalline Ni3 P besides molten Ni. In the case of Ni68.8P31.2 , the first peak in the pair correlation function was modelled using the distance and coordination number as in crystalline Ni2P.
