Longitudinal acoustic velocities have been measured for liquids in
the system Na2O---Al2O3---SiO2 spanning much of the composition range
Na2SiO3---NaAlSiO4---SiO2. Measurements were made at temperatures
between 1185C and 1620C, using the technique of ultrasonic interferometry.
Sound speeds, and therefore bulk moduli, show a general increase
with increasing alumina content. This trend is explained qualitatively
in terms of a molecular model of the effect of sodium and aluminum
on the structure and dominant compression mechanism of silicate liquids.
We present a computational model for estimation of both sound velocities
and isothermal compressibilities within much of the compositional
ternary Na2SiO3---NaAlSiO4---SiO2. Implications of these results
for the high pressure anhydrous melting curve of albite (NaAlSi3O8)
are also discussed. Acoustic velocities are presented for liquid
sodium chloride in order to provide a basis for comparison with data
from other laboratories.
