　　Polycrystalline samples of Ca9Co9M3O28 (M=Mn, Fe, Ni, Cu) have been synthesized through a simple citrate-gel method.The temperature dependence of the electrical resistivity has been carefully examined from room temperature to 1000 K.The Mn-substituted samples, similar with Cu substitution show the metallic like behavior (dp/dT>0) in all the measured temperature range.
