Abstract

The Bi2O3‐rich side of the system Bi2O3‐SiO2 was studied with powder X‐ray diffraction and differential thermal analysis. In the composition 6Bi2O3. xSiO2, the metastable γ phase (bcc) was observed to exist over the range of 0 < x≤ 1. In most of the compositions studied, metastable phases of water‐quenched melts transformed into another metastable phase before reaching stable phases. A modification of the phase diagram is proposed. Copyright © 1990, Wiley Blackwell. All rights reserved
