Abstract Highly textured Bi 2 Sr 2 Ca 1 Cu 2 O 8+δ (Bi-2212) tapes were prepared on both sides of 50μm thick Ag substrates in alternating electrolytic depositions and heat treatments. We hve found that very small changes in stoichiometry can affect the melting behaviour of the Bi-2212, the volumic fraction of the alkaline earth cuprates phases and consequently can influence the J x (77K, Ot) values of the tapes. Optimisation of the process leads to samples exhibiting very high J c value up to 40 000A.cm −2 , in self-field at 77K.
