Mineral maturity and crystallinity index are distinct characteristics of bone mineral [PDF]

, 2010
The purpose of this study was to test the hypothesis that mineral maturity and crystallinity index are two different characteristics of bone mineral. To this end, Fourier transform infrared microspectroscopy (FTIRM) was used.
