Abstract
The flow and bubbles motion in BaO-P2O5 or BaO-P2O5-Sb2O3 glass melts in a high magnetic field up to 2.0 T was observed. No apparent change of how cha racteristics in BaO-P2O5 glass melts was found. However, the frequency of b ubble nucleation evidently decreased with the held strength. At a held stre ngth of 2.0 T, almost no nucleation of bubbles was observed. The majority o f the bubbles were annihilated at the surface of the melt. This effect may apply to many optical quality glasses to be obtained bubble-free.
