摘要: Diffusion of gold in lead has been investigated by means radioactive tracers method the range temperatures between 190 and 300 ‡C. In this temperature interval experimental values diffusion coefficientD fit equation\(D = 2.8 \cdot 10^{ - 3} \exp \left[ {\frac{{8.91 }}{{RT}}} \right]cm^2 s^{ 1} \) whence an activation energyQ (8.91 ± 0.18) · 103 cal mole-1 is obtained.
