Abstract

The electron-doped bismuth oxide (Ba0.6Bi0.4)BiO2.92 has been successfully synthesized by the two-step heating method. Mixed powders of the starting materials have been pelletized and heated in flowing gas of N2 at 800 °C for 12 h. The reacted pellets have been heated at 400 °C first in flowing gas of O2 for 24 h and then under a high oxygen-pressure of 600 atm at 400 °C for 96 h. It has crystallized in a pseudo-cubic symmetry. From the X-ray diffraction and inductively coupled plasma analyses, the substitution of Bi for Ba has been confirmed, but the product has still remained an insulator.
