Screen-printed Bi 1.84 Pb 0.34 Sr 2.03 Ca 1.9 Cu 3.06 O y superconducting thick films were prepared on MgO substrates from powder consisting almost entirely of the 110 K phase, and the thick film sandwiched between the two MgO substrates was further hot-pressed in air. Under the hot-pressing condition of 500 kg/cm 2 at 855°C for 30 min, the T c and resistivity at 270 K were 105 K and 6.1×10 -4 Ω·cm, respectively. The J c was 4800 A/cm 2 at 77 K in zero magnetic field. The relationship between superconducting properties and hot-pressing conditions was examined.
