We have studied electronic properties of (YBa2Cu3O6.9)1-xAgx compounds with 5, 10, 15, 25 and 50 wt% Ag. In our samples, the silver fills the intergranular space and the superconductivity is preserved even at 50 wt% Ag(Tc=87 K). These samples can be safely dropped in water without loss of superconductivity. The magnitude of electrical resistivity at 300 K rapidly decreases from 103 μΩcm for 5 wt% Ag down to approximately 30 μΩcm for 50 wt% Ag. The superconducting transition is always around 92 K. Preliminary measurements on the samples with 5 wt% Ag indicate at least factor of 2 improvement in the critical current.
