中文摘要	The effect of Ag addition (0-20 wt%) on polycrystalline Sr0.6K0.4Fe2As2 superconductor has been investigated. It is found that the critical transition temperature T-c was not depressed, and the irreversibility field H-irr and hysteresis magnetization were significantly enhanced upon Ag addition. A characterization study reveals that larger grains are observed in the Ag-added samples. Moreover, the formation of a glassy phase as well as an amorphous layer, which are present in almost all the grain edges and boundaries in pure samples, are suppressed by Ag addition. The improvement of superconducting properties in Ag-added samples may originate from the enlargement of grains as well as better connections between grains
