The short-range structure of 20BaO-80TeO glass was studied by high pressure neutron diffraction and high pressure Raman spectroscopy. Neutron diffraction measurements were performed at the PEARL instrument of the ISIS spallation neutron source up to a maximum pressure of 9.0 ± 0.

The bismuth tellurite system forms glasses at low BiO concentration of 3 to 7 mol%. At 20 mol% BiO, the glass forming ability of the BiO-TeO system decreases drastically and the anti-glass phase of monoclinic BiTeO is produced.
