The temperature and amplitude of AC field dependencies of both inter- and intragranular T{sub p} and T{sub g} temperatures of the imaginary peaks of {chi}{double_prime} has been studied for a sintered single phase (Bi,Pb):2223 superconductor. The AC field dependencies for T{sub p} and T{sub g} and the relation between inter- and intragrain force densities were discussed by using Mueller critical-state model. From the {chi}{double_prime} curve, the values of intergrain magnetic critical current density J{sub cJ} was obtained via the application of Beans` critical state model. J{sub cJ}(T) dependence near {Tc} agree with the assumption of SNS intergrain junctions.
