Pseudo-binary sodium borate glasses containing (1 − y)Na2B4O7–yMaOb (where MaOb = PbO, Bi2O3 and TeO2) (y = 0.25, 0.5, 0.67 and 0.79) have been investigated. Sound velocities (longitudinal and shear) have been measured at 10 MHz frequency using quartz transducers. Density increases with increase of y and the molar volume decreases...
