Abstract
The common mechanism is suggested to illuminate superconductiviy of Onormal metallic and high Tc superconductors,which is based on the electron phonon interaction, the interaction among lattice screened electrons and that of electronic spins.It is showed that the mechanism of both MgB2 superconductivity and ceramic superconductivity is due to reduction of the number of free electrons,by which the formula of BCS can be mended,leading to the prediction that the critical temperature of Li2O is higher than that of MgB2.
