Understanding the Crystallinity Indices Behavior of Burned Bones and Teeth by ATR-IR and XRD in the Presence of Bioapatite Mixed with Other Phosphate and Carbonate Phases

Figure 4

Magnification of the band evolution; we may envisage a complex progression of signals. In this case, the values of SF do not present an increasing monotonic trend with temperature but remain nearly constant around 3.3-3.4. Note the shoulder which appears at about 547 cm⁻¹ attributable to β-TCP phase.
