Modification of the density-pressure relationship due to the internal friction and cohesion of a powder mass undergoing closed die compaction Miriam Kupková Institute of Materials Research of SAS, Watsonova 47, Košice, Slovakia mkupkova@imr.saske.sk Keywords: Density-pressure relationship, die compaction, internal friction, cohesion Abstract.
The existing density-pressure laws for a powder undergoing die compaction fit experimental data very well except for the low-pressure end of curves for some materials (SiC, Al2O3).
K is a material constant quantifying the ability of compact to deform.

The results confirmed that CHA are potential bone-grafting materials and also showed that CFA, compared to CHA or HAP materials, accelerate bone formation.
The implanted materials were covered with biodegradable membranes to prevent material loss during the experiment.
However, these materials differed in extent of resorption with CHA being the fastest and HAP the slowest.
These results confirmed that carbonate-containing apatites are potential bone-grafting materials.
The results also showed that CFA, compared to CHA or HAP materials, accelerate bone formation attributed to the F content.
