✦ Synopsis

The short range structure of (1 Ϫ x)B 2 O 3 -xRb 2 O (x 0.05-0.30) glasses was investigated to study by time-of-flight neutron scattering experiments using the high intensity total scattering spectrometer (HIT). In each correlation function of G(r) curve, the first peak appeared at around r 1.4 A ˚which was thought to be due to the B-O correlation in boroxol ring composed of trigonal planer BO 3 units and tetrahedral BO 4 units. The results in the short range structure of borate glasses were similar to those which were calculated by two molecular orbital methods.

Lithium borate glasses containing TeO 2 as Li 0.6 Te x B 1.4À2x O 2.4Àx have been prepared by the conventional rapid quenching method over a wide range of composition (x ¼ 0, 0.1, 0.2, 0.3, and 0.35). Ultrasonic velocities (longitudinal and shear) were measured in these glasses at room temperature.
