| Abstract | Structural transformation of alpha-Bi2CuO4 (a = 8.4996 Angstrom, c = 5.8172 Angstrom, space group P4/ncc) during ball milling was investigated by powder x-ray diffraction and thermal analysis. It is shown that alpha-Bi2CuO4 first transforms into an amorphous phase; and then transforms into a new phase (designated by beta-Bi2CuO4) with milling time. The new phase appears to be isostructural to (La,Sr)(2)CuO4 and has a tetragonal cell with cell parameters a = 3.869 and c = 13.83 Angstrom. It is a metastable phase which can transform back into alpha-Bi2CuO4 at 650 degrees C. No superconductivity was observed above 5 K for both as-milled samples and oxygen-annealed beta-Bi2CuO4.
