Abstract
Chemical and mechanical stability of the high-Tc phase has been studied for the samples of Bi0.9Pb0.2Sr1.0Ca1.0Cu1.6Ox. Mechanical grinding converts the high-Tc phase into a nonsuperconducting amorphous phase. The ground high-Tc phase is not stabilized on annealing at lower temperatures below820»C. Annealing at lower temperature leads to precipitation of some impurity phases and the low-Tc phase which depends on annealing temperature and time. The high-Tc phase is recovered by annealing at 850»C. The lattice parameters a and c of the high-Tc phase annealed at 850»C are longer than those below 820»C.
