Newly discovered MgB2 superconducting tapes have been prepared by PIT process. The critical current (Ic) of the Ni-sheathed MgB2 tapes with 10vol% In and Sn addition excesses 300A at 4.2K, corresponding to above the critical current density (Jc) of 40, 000A/cm2. The addition of powder metals with low melting point improves the Ic for the MgB2 superconducting tapes.
