Abstract

The heat of transport,Q*, for cobalt in α-thorium was determined by a combination of single-phase, steady-state and two-phase, nonsteady-state techniques. The heat of transport,Q*, is temperature-dependent, decreasing from +20 kj/mol at 1125 K to s-60 kJ/mol at 1460 K. This is best described by a linear relation,Q* = 214 s-0.24T kJ/mol. The observed temperature dependence ofQ* can perhaps be attributed to the electronic contribution to the heat of transport, as postulated in Hehenkamp’s model.
