• We have measured the resistivity of the Ag-Bi_2Sr_<1.8>Ca_<1.2>Cu_2O_y composite system with Ag volume fraction p_<Ag> ranging from 0.00 to 1.00. We find, for the samples with p_<Ag><0.6, that the addition of Ag slightly decreases the superconducting transition temperature of Bi_2Sr_<1.8>Ca_<1.2>Cu_2O_y. For the samples with p_<Ag>>0.6, no zero-resistivity state is observed. The variation of the room-temperature resistivity with p_<Ag> indicates a three-dimensional percolating Ag matrix occurring at p_<Ag>≈0.17.
