N2 - The thermal conductivity and the electrical resistivity of highly c-axis oriented polycrystalline Bi1.85Pb0.35Sr1.90Ca2.05Cu3.05Ox in a magnetic field have been measured in the temperature range from 4.2K to 140K. The main heat carriers are phonons. The phonon thermal conductivity was analyzed by using the Tewordt-Wölkhausen expression. It indicates that phonon-phonon scattering due to umklapp process is important above 30K. For the depression of the thermal conductivity below Tc in magnetic fields, the scattering due to fluxoids was considered.
