Fig. 4From: Influence of Thermal Treatment on the Antimicrobial Activity of Silver-Doped Biological ApatiteInfrared absorption spectra of the AgHAp (xAg = 0.5) before thermal treatment (a) and after the thermal treatment at 600 °C (b) and 1000 °C (c). The bands attributed to the water lattice (3550–3600 cm−1) are presented in the top right corner of each spectrumBack to article page
