摘要：

TeK-edge spectra were measured for binary glasses of compositions 0.16B2O3.0.84TeO2 and 0.301B2O3.0.699TeO2. Te-O bond length and coordination number of Te atoms were analyzed to be very similar to those of paratellurite. Within errors of measurement, all the Te atoms were four-coordinated and TeO3+ units were absent in the glasses. It was concluded that some other mechanism should be present to compensate for a negative charge on four-coordinated boron atoms in the glasses.
