Assessments of Shrinkage Degree in Bioceramic Sinters HA+ZrO2
In the aspect of growing popularity of hydroxyapatites and HA-based composites (with addition of ZrO2 phase) used in medicine, it seems to be crucial to determine accurate percentage content of ZrO2 phase addition in the mixture ensuring invariable or predictable changes in dimensions of implants or coatings after the process of sintering. In consideration of the aforementioned statement, combined mathematical and statistical analysis enabling prediction of such changes was carried out.
