Abstract

A known approach to mathematical description of the compaction process for monodispersed spherical powders under hot isostatic compression is developed for actual polydispersed powders. Calculated compaction curves for silicon nitride agree satisfactorily with experimental data. Estimation of grain-boundary diffusion parameters gives values of 6 · 10−18 m3/sec and 180 kJ/mole which corre-spond to results obtained in other experimental works.
