Abstract
The thermal stability field of Bi2Sr3Cu3O8 in the Bi-Sr-Cu-O system ha s been investigated using an apparatus for combined high-temperature X -ray powder diffraction and optical microscopy. Bi2Sr3Cu2O8 starts to decompose at 910 +/- 2 degrees C and changes into Bi4Sr8Cu5Ox through a transient state of melting and subsequent solidification. Bi4Sr8Cu5O x decomposes into SrCuO2 at 915 +/- 2 degrees C with increasing amount s of the liquid phase, and becomes 3 completely liquid state above 101 0 +/- 2 degrees C.
