• The effect of the sintered density on the transport properties like normal state resistivity, T_c (superconducting transition temperature) and absolute thermopower has been studied for doped YBCO (YBa_2Cu_<3-x>M_xO_<7±y>, where M=Ti^<4+>, V^<5+>, Cr^<3+> or Mn^<4+> and x=0.0-0.1 g atom). The sintered density of the sample depends on the valency of the substituent. The density increases in the order pure YBCO<Cr^<3+> doped YBCO<Ti^<4+> doped YBCO<Mn^<4+> doped YBCO<V^<5+> doped YBCO. The resistivity as well as absolute thermopower decreases with increasing density. The significance of these results for the technological applications of granular superconductors is briefly discussed.
