Abstract: The total structure factors, S(Q) of 50:50 mole% CaO:Al2O3- and 67:33 mole% SrO:Al2O3-composition liquids have been determined by neutron diffraction. Measurements were made on laser beam-heated liquids at 2000–2100 K held in an aerodynamic levitator. Pure vanadium levitation nozzles were used. Reduction of the nozzle wall thickness decreased attenuation of scattered neutrons to give a two-fold increase in signal intensity. The liquids are comprised of predominantly 4-coordinated aluminum and 6- and higher-coordinated group II metal ions.
