• A new method of X-ray diffraction measurement widely applicable to fused materials including corrosive substances up to high temperature ranges has been described. By the Fourier Analysis of X-ray diffraction data, the atomic radial distribution curves of several fused materials have been obtained. Fused NaNO_3 and NaNO_2 contain Na^+ ions and NO_3^- or NO_2^- radicals, which are in thermal motion being restricted by their specific shapes and charge distributions. The structure of fused PbO-B_2O_3 system in the range of PbO/B_2O_3=4/1 to 1/3 in mol-ratio are, in general, considerably similar to their glass, but Pb-O bonds become more ionic by the fusion or by the increase of B_2O_3 content. Its abnormal glass-forming-limit (94 wt % in PbO) is also explained.
