Hydroxyapatite and Hydroxyapatite-Based Ceramics
Data are summarized on the synthesis of hydroxyapatite (HA) by wet-chemical processes, solidstate 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. Detailed analysis of the fabrication and properties of calcium-phosphate-based ceramics is presente...
متن کاملPreparation of hydroxyapatite from animal bones.
This paper presents the method of obtaining hydroxyapatite from animal bones. Bone sludge and calcined products were characterized by X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Calcium concentration was determined with titration, and phosphorus--spectrophotometrically. Making use of the AAS and ICP methods the content of mi...
متن کاملNatural radioactivity of some Egyptian materials used in glasses manufacturing and glass ceramics
Background: The new glasses from harmful environmental waste such as cement dust; limestone phosphate, sand and borax (Genkare) were manufactured. Investigation of the radioactivity present in these materials (Phosphate rock, cement dust, limestone, sand and borax) enables one to assess any possible radiological hazard to humankind by such materials. Materials and Methods: Fifteen samples were ...
متن کاملSynthesis, Characterization and In Vitro Study of Synthetic and Bovine-Derived Hydroxyapatite Ceramics: A Comparison
The physicochemical properties and biological behavior of sintered-bovine-derived hydroxyapatite (BHAp) are here reported and compared to commercial synthetic-HAp (CHAp). Dense ceramics were sintered for 2 h and 4 h at 1200 °C to investigate their microstructure-structure-in-vitro behavior relationship for both HAp ceramics. Densification was directly proportional to sintering time, showing a g...
متن کاملPreparation of Higly Porous Hydroxyapatite Ceramics from Cuttlefish Bone
Abstract: Hydroxyapatite, Ca10(PO4)6(OH)2, has been widely investigated for medical purposes because it is suitable for either direct clinical use as implants or tissue-engineering applications. In this work materials were successfully produced via hydrothermal transformation of aragonite, obtained from fresh cuttlefish bones, at 200°C and high pressures. Beyond low production cost, worldwide a...
