The X-ray diffraction showed that all the solid samples were pure apatite
with crystallizing in the hexagonal system [P6.sub.3]/m, which was confirmed by comparing with the JCPDS reference for cadmium hydroxyapatite (00-014-0302) (Figure 1).
Time-dependent luminescence measurements show a bi-exponential decay behaviour for each investigated [Eu.sup.3+] doped apatite
, which can be explained by the two distinct sites occupied by [Eu.sup.3+] within the apatite
structure (see Fig.
present in minor amounts and usually forming grains < 0.2 mm (occasionally up to 1 mm) in size is described.
Source of trace elements in human body is via ingestion of food or on exposure to the environment, incorporated into the apatite
structure of the enamel.
bone cement reinforced with calcium silicate fibers," Journal of Materials Science: Materials in Medicine, vol.
used in this work was obtained from Hazm Al-jalamid area, northern Saudi Arabia.
These properties confirmed the samples were apatite
The growth of apatite
on TNTA and Zn-TNTA specimens was studied by in-vitro immersion studies in Hank's solution for a period of 14 days.
The scleractinian coral genus Goniopara, which possesses a microstructure resembling that of cancellous bone, has been converted to hydroxy apatite
[Coralline Hydroxy Apatite
Goniopora (CHAG)], chiefly for use as an alternative to autogenous grafting in the management of residual subchondral osseous defects following elevation of depressed articular fragments of epiphyseal-metaphyseal long bone fractures.
Lu-Hf isotope systematics of fossil biogenic apatite
and their effects on geochronology.
Non-metallic minerals are apatite
, quartz, hornblende, actinolite, epidote, chlorite, Saussure, pomegranate.
1), we used the apatite
fission-track (AFT) geochronology technique.
