Application of a mathematical model for description of consolidation and compaction processes of uranium dioxide powders

A mathematical model allowing one to analyze consolidation and compaction processes of uranium dioxide powders of ceramic grade and mixtures based on it is suggested and confirmed experimentally. The model makes it possible to predict the final parameters of powder products that are simple in form starting from the results obtained during testing of the powders on the basis of the deformation function of a powdered body at two pressing pressures without subsequent sintering. This decreases the time and expense compared to the technological testing used in industry.
