Abstract
The single‐crystal elastic stiffnesses of fluorapatite, Ca5F(PO4)3, have been measured by an ultrasonic technique. The values are: C 11=152.0, C 12=49.99, C 13=63.11, C 33=185.7, and C 44=42.75 GPa. These results are compared with previously published values to resolve anisotropy contradictions and differences in magnitude. The apatitecrystal structure is not very elastically anisotropic. It suggests that the elasticanisotropy of bone derives primarily from the hierarchical microstructure of that biocomposite and not from the anisotropy contribution of the apatite mineral component.This publication has 7 references indexed in Scilit:
