This paper reports on the high temperature resistivity ({rho}), thermogravimetry (TG) and derivative thermogravimetry (DTG) which have been used to characterize superconductor Ba{sub 2}YCu{sub 3}O{sub 7{minus}x} (BYCO) in O{sub 2}, air and N{sub 2}. The resistivity is linear from room temperature to 350{degrees} C and then deviate from linearity with oxygen evolution, the derivative of resistivity d{rho}/dT increases abruptly near orthorhombic to tetragonal phase transition. These phenomena can give good explanations for a two-band Drude model.
