Tracer diffusion of 110Ag in Bi2Sr2CaCu2Ox
Abstract
Tracer diffusion of 110Ag in dense polycrystalline Bi2Sr2CaCu2Ox has been measured at temperatures from 600 to 800 °C at an oxygen pressure of 105 Pa, and in oxygen partial pressures from 103 to 105 Pa at 700 °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.
