Abstract	Although just recently discovered as a superconductor, Magnesium Diboride has already demonstrated its clear potential for an effective use in a variety of applications. With its critical temperature of about 40 K, MgBB2 gives the opportunity to operate devices at cryogenic temperatures of the order of 20 K, allowing for the use of alternative, cost effective, and simpler technologies than liquid helium. Suitable processes for long lengths wire manufacturing have been demonstrated in the recent years. This work will focus on the preparation of MgB2B based superconducting wires by the Powder-In-Tube method, using the so-called ’ex-situ’ process. The main physical and structural characteristics of these wires will be finally reported and briefly discussed.
