Abstract:
The purpose of the dataset is to present the morphological features,
elemental composition and functional groups of hydroxyapatite
(HAp) synthesized from non-separated biowastes (animal
bones) by a modified facile heat treatment method up to a
maximum temperature of 1100 C. The synthesized powders were
characterized using scanning electron microscopy (SEM) equipped
with electron dispersive X-ray analysis (EDX) and Fourier transform
infrared spectroscopy (FTIR). These evaluations were to
reveal the surface features, elemental composition and identify the
functional groups of the synthesized powders. After heat treatment
of the raw biowastes to 900 C, 1000 C, and 1100 C (regime
of heat treatment), the morphological features of the samples
exhibited a more densely packed microstructure at the highest
sintering temperature (1100 C). The elemental composition as
evaluated by EDX on a weight and atomic basis for all samples
provided information on the calcium to phosphate transforms into
apatite with a Ca/P ratio of 3.60, 2.04, 2.50 and 2.32 wt % and 2.79,
1.58, 1.94 and 1.78 at. % respectively for raw biowastes (RB) to
sintered samples (HA-900, HA-1000 and, HA-1100 C). The FTIR
data showed phosphate and hydroxyl peaks in the thermally
treated samples and all the samples produced characteristic stretching modes of OeH bands at about 3417 cm 1 which are
noticed in all FTIR spectra of HAp.
