Hydroxyapatite Synthesis and Comparison with Commercial Hydroxyapatite

Journal of New Results in Science, 2016
Hydroxyapatite HAs is the most commonly used synthetic, inert, and biocompatible material having no organic substance. HA having calcium phosphate in their structures are biomaterials used in injured organs or tissues in human body. These make quick and strong recovery when used in body.

Calcium-deficient Hydroxyapatite as a Potential Sorbent for Strontium

Scientific Reports, 2017
A calcium (Ca)-deficient hydroxyapatite was investigated for its potential to remove Sr2+ from environmentally relevant water. We conducted sorption tests on solutions containing magnesium ion (Mg2+) and calcium ion (Ca2+) as competing cations at a ...

Application Of Hydroxyapatite In Protein Purification

Makara Seri Sains, 2009
The precursors, Na2HPO4.2H2O and CaCl2.2H2O are used for synthesizing pure hydroxyapatite which less of carbonatecontent. The high temperature of sintering, about 700oC of temperature, is treated to minimize the carbonate group onhydroxyapatite surface ...

Synthesis and characterization of hydroxyapatite, fluoride-substituted hydroxyapatite and fluorapatite

Journal of Materials Science: Materials in Medicine, 2003
Powders of hydroxyapatite (HA), partially fluoride-substituted hydroxyapatite (fHA), and fluorapatite (FA) were synthesized in house using optimum methods to achieve relatively pure powders. These powders were assessed by the commonly used bulk techniques of X-ray diffraction (XRD), Fourier transform infra-red (FTIR) and FT-Raman spectroscopies ...

Synthesis and characterization of hydroxyapatite/SiO2/gelatin composites as bone scaffold candidates

Communications in Science and Technology
This study aims to determine the characteristics of hydroxyapatite/SiO2/gelatin composites to fulfil the bone scaffold standards. XRF analysis showed that limestone has a high CaO content of 92.89%, allowing it be used for hydroxyapatite synthesis.

Hydroxyapatite coating of prostheses [PDF]

The Journal of Bone and Joint Surgery. British volume, 1991
The basic problem with the fixation of a prosthesis, cemented or cementless, is biomechanical. The forces transmitted between it and bone will depend on the design and the surface geometry of the implant, the mechanical properties of its surface, and the operative technique.

Ostrich eggshell as calcium source for the synthesis of hydroxyapatite and hydroxyapatite partially substituted with zinc

Cerâmica
In the present study, hydroxyapatite and Zn-substituted hydroxyapatite powders were synthesized using ostrich eggshell as a calcium source. The samples were analyzed by scanning electron microscopy with field emission gun, and X-ray diffraction (XRD) to ...
