The present paper describes calcination of pure and Zn doped hydroxyapatite (HA) (of different mol %) at four different temperatures for observing the sintering behavior and concentration effects. Doped and un-doped apatites were synthesized from waste egg shell as Ca precursor through precipitation method. The substituting limit was up to 8mol%. The influence of sintering condition on phase composition was evaluated by using Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD) and scanning electron microscopy SEM techniques. Presence of Zn was confirmed from x-ray fluorescence (XRF) and electron diffraction spectroscopy (EDS) analyses. Crystallographic values were calculated and comparable discussion was presented. Observed data were also in excellent agreement with the standard values for HA.

Sodium doped hydroxyapatite (HA) (of different mol%) was calcined at four different temperatures for observing the sintering behavior and concentration effects. Doped and pure apatites were synthesized from waste egg shell as Ca precursor through precipitation method. The substitution limit was up to 8mol%. Atomic absorption (AAS) and UV spectrophotometric methods were followed to detect the presence of Na, Ca, P etc. Quantitative analysis was carried out by X-ray fluorescence (XRF) and electron diffraction spectroscopy (EDS). The influence of sintering temperature on phase composition was evaluated by using Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD) and Scanning electron microscopy SEM techniques. Crystallographic values were calculated and comparable discussion was presented. Observed data were also in excellent agreement with the standard JCPDS values for HA.
