摘要：

Nanosize MgO and TiO2 particles were added to the Bi2Sr2CaCu2Ox, powder with 20% molar fraction. Powder-in-tube Ag-sheathed tapes were made from the doped powders and heat treated by partial melting processing, Heat treatment optimization was carried out to increase the critical current density, Scanning electron microscopy and energy-dispersive Xray spectra were used to study the phases present in the tapes, The effect of MgO additions on the flux pinning behavior was investigated by magnetic hysteresis and transport critical current measurements at various temperatures and fields.
