After annealing at 800 ℃ for 2, 12 and 96 h, critical temperature Tc of the samples measured by four probe method is 17 K. Critical curreds Ic was measured in the function of temperature and applied field in a split pair magnet. The relationship of normalized pinning force vs applied field follows simple Kramer equation. Grain boundaries were most probable pinning source for the magnetic line of force. The obtained upper critical field Bc2 existed a linear relation with the temperature. A critical surface of Ic - T - B was also plotted from the measurement of critical current.
