Observations of the natural surface of BiSrCaCu₂Oₓ sintered ceramics applying the
scanning tunneling microscope are reported. Measurements were performed in air at room
temperature. It can be deduced from the surface images, on which the growth steps are visible with
heights corresponding to the dimension of the unit cell along the c-axis or its multiples, that the bulk
orthorhombic structure extends to the surface. The surface investigated is rather clean, inert and
metallic in nature. It can be identified as the Bi-O layer.
