Abstract: The aim of the paper was to show if the acoustic emission (AE) signals from BiSrCaCuO ceramic superconductors appear during normal state–superconductivity transition. These AE signals were previously observed from YBaCuO-type superconducting materials. The BiSrCaCuO samples were prepared and characterised. The resistance–temperature and current–voltage characteristics of these samples were measured. The critical temperature and critical current density were estimated. AE was measured from samples with and without current flow. The AE signals during sample temperature rise were observed at temperature near the critical value.
