Measurements are obtained by synchrotron X-ray scattering on levitated, laser-heated liquid specimens. The S(Q) shows a prepeak at 2.0 {\AA}−1 followed by a main peak at 4.5 {\AA}−1 and a weak feature at 8 {\AA}−1. The G(r) shows a strong (Si,Al)--O correlation at 1.80 {\AA} at high temperature that moves to 1.72 {\AA} as the liquid is supercooled. The second and third nearest neighbor peaks at 3.0 and 4.25 {\AA} sharpen with supercooling. The short-range structure of the high-temperature liquid is similar to the corresponding glasses produced by rapid quenching. Supercooling causes an increase in the concentration of tetrahedral Si4+ ions, which is manifested by the large shift in the first peak to lower ionic distance, r, values in G(r). The increase in tetrahedrally coordinated Si4+ ions is offset by an increase in octahedral Al3+ ions. The clustering of the SiO44− tetrahedral units results in increased viscosity of the liquid at temperatures below the melting point, which is consistent with Al6Si2O13 being a fragile liquid.}, Author = {Krishnan, Shankar and Weber, J.
