Thermoluminescence in hydroxyapatite

Medical Physics, 1979
A thermoluminescent (TL) glow peak has been shown to exist at 80°C in synthetic hydroxyapatite, in amorphous calcium phosphate, and in deproteinated rat bone mineral. This TL glow peak is excited by a thermal pretreatment at elevated temperature, followed by exposure to ultraviolet (UV) light. When measured on a cylic TL‐readout UV‐exposure basis after

Monoclinic Hydroxyapatite

Science, 1973
The existence of a monoclinic phase of hydroxyapatite, Ca 5 (PO 4 ) 3 OH, has been confirmed, by single-crystal structure analysis (weighted "reliability" factor = 3.9 percent on |F| 2 ). The structure has space group P 2

Hydroxyapatite and Hydroxyapatite-Based Ceramics

Inorganic Materials, 2002
Data are summarized on the synthesis of hydroxyapatite (HA) by wet-chemical processes, solid-state reactions, and hydrothermal treatment. The conditions for HA preparation via precipitation from solutions of calcium chloride, dibasic ammonium phosphate, and aqueous ammonia are discussed at length.

Comparison of hydroxyapatite and hydroxyapatite tricalcium-phosphate coatings

The Journal of Arthroplasty, 2002
This study compared the effects of hydroxyapatite (HA) coating and biphasic HA/tricalcium-phosphate (HA/TCP) coating on the osseointegration of grit-blasted titanium-alloy implants. Each coated implant was compared with uncoated grit-blasted implants as well.

Nanofiber generation of hydroxyapatite and fluor‐hydroxyapatite bioceramics

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005
AbstractIn this study, we produced hydroxyapatite (HA) and fluor‐hydroxyapatite (FHA) bioceramics as a novel geometrical form, the nanoscale fiber, for the biomedical applications. Based on the sol‐gel precursors of the apatites, an electrospinning technique was introduced to generate nanoscale fibers.

Adsorption of Catalase on Hydroxyapatite

Journal of Colloid and Interface Science, 1998
The adsorption of catalase on calcium hydroxyapatite is reported in this study. In all the solutions investigated, catalase adsorption takes place under conditions where the adsorbent and the adorbate are both negatively charged and is accompanied by the release of phosphate ions. This suggests that electrostatic attraction does not play a leading role

HYDROXYAPATITE COATINGS

Orthopedics, 1994
ABSTRACTA series of investigations over the past several years has evaluated a number of implant materials with and without plasma-sprayed hydroxyapatite (HA) coatings for use in load-bearing implant applications. HA-coated implants have exhibited greater interface shear attachment characteristics when compared to uncoated implants; these results have ...

Hydroxyapatite Coatings

Clinical Orthopaedics and Related Research, 1988
Significant interest for orthopedic surgical applications of hydroxyapatite compounds is based on a number of reasons including the elemental chemistry of the primarily calcium and phosphate ion substances, the controllability of the crystalline and physical structures to provide a wide range of in vivo interactions, the existing literature on ...
