β-Tricalcium Phosphate Interferes with the Assessment of Crystallinity in Burned Skeletal Remains

Figure 4

ATR-IR spectra of three human teeth heated at 1050°C that are particularly noteworthy because they present a significant amount of β-TCP (from bottom to top, T1 = 44 wt%, T3 = 42 wt%, and T4 = 25 wt%, resp.) detected with XRD. The deformation of the band is observable, as well as the presence of an additional peak at 1123 cm⁻¹ (in T1 and T2 specimens) due to the presence of β-TCP.
