Conclusions
We note in conclusion that not a single one of the existing pressing equations encompasses completely the entire range of pressures and densities. Moreover, the problem of the use of one or another formula cannot be solved without regard to practical conditions which occur during compacting and without those requirements which the compacts should satisfy.
