Abstract

The background, theoretical and experimental requirements of powder compaction equations have been briefly reviewed in this paper. There have been many equations proposed but none has proven to reflect both powder properties and to be successfully applied in research and development and production environments. However, the equations most commonly used are Heckel and Kawakita ones, because they alone have claimed to be able to relate to the physical properties of the materials being compacted. In this article, advantages, limitations and modifications of some of these compaction equations have been discussed.
