Abstract

Compressional and shear wave velocities have been measured as functions of pressure up to 2 GPa for float glass and SiO2+8.4wt%TiO2 glass using pulse superposition method.The compressional wave velocities for float glass are found to increase first,then decrease with increasing pressure.This phenomenon is different from that of other glasses.The shear wave velocities of float glass and both compressional and shear wave velocities of SiO2+8.4wt%TiO2 decrease with increasing pressure as general SiO2 glass.The experimental results are discussed.And the state parameters in Murnaghan equation have been calculated.
