摘要：

Tracer diffusion of Ag-110 in dense polycrystalline Bi2Sr2CaCu2Ox has been measured at temperatures from 600 to 800-degrees-C at an oxygen pressure of 10(5) Pa, and in oxygen partial pressures from 10(3) to 10(5) Pa at 700-degrees-C. The diffusivity of Ag in Bi2Sr2CaCu2Ox is given by D = (8.9(-4.2)+7.9)exp[-(181.4 +/- 4.8 kJ/mol)/RT] cm2/s, and is not a sensitive function of oxygen partial pressure.
