Abstract
Sintering in compacted Molybdenum powders is investigated using small angle neutron scattering. The scattering data permits to follow the evolution of the total pore surface F together with the total pore volume V in the course of the entire densification process. Characteristic changes in the relation between F and V suggest that, in particular, final stages of sintering (when the porosity can already be considered isolated from each other) are governed by a universal relation between F and V [1].
