Notes:
The single-crystal elastic stiffnesses of fluorapatite, Ca5F(PO4)3, have been measured by an ultrasonic technique. The values are: C11=152.0, C12=49.99, C13=63.11, C33=185.7, and C44=42.75 GPa. These results are compared with previously published values to resolve anisotropy contradictions and differences in magnitude. The apatite crystal structure is not very elastically anisotropic. It suggests that the elastic anisotropy of bone derives primarily from the hierarchical microstructure of that biocomposite and not from the anisotropy contribution of the apatite mineral component.
