Two routes have been followed in order to prepare Bi~.7Pbo.3Sr2Ca2Cu3Oy superconducting materials. Bil.TPbo.3CuO 4 is always used as one of the starting basic materials. The first route involves a new experimental procedure based on the solid state synthesis of separate intermediate phases, mixed to
