ICP-MS measurement of silver diffusion coefficient in graphite IG-110 between 1048K and 1284K

The measured activation energy of 174 kJ/mol compares well with the range of values [154-193 kJ/mol] reported in the literature for LTI pyrocarbon. The measured pre-exponential D0 value of 6.60 × 10−4 m2/s is similar to the value of 5.3 × 10−4 m2/s reported for Russian LTI pyrocarbon.
