Abstract
We have synthesised Ba0.6K0.4BiO3 (BKB) and BaPb1-xBixO3-y compounds by sol-gel process. IR spectra of gels indicated the bridging type of bonding between metal carboxylates leading to the formation of homogeneous gels. BKB and BaPb0.75Bi0.25O3 compounds exhibited sharp superconducting transitions from R-T and χ-T measurements indicating excellent homogeneity of the samples. © 1994.
