“…where Experimental data [7,9,10] correlate satisfactorily with the results of calculations using models of generalised conductivity (equations (1) to (3) and (6)) only in the case of a highly dispersed filler with isotropic particles of quasispherical shape. However, in this case it is necessary to take into account the specific nature of the thermophysical properties of the transition layer formed at the filler particle/ binder boundary.…”
