Synthèse de phosphate de calcium pour la fabrication de biocéramiques

62.31 x 41.59 cm / 300 dpi


Synthesis of calcium phosphate for the manufacture of bioceramics with an apatite structure, analogous to bone mineral. These ceramics, more specifically in this case hydroxyapatite, are used to manufacture bone substitutes for bone tissue engineering. The main reactor contains calcium nitrate, to which is added, at a controlled temperature and pH, ammonium phosphate. This synthesis using soft chemistry makes it possible to obtain a calcium phosphate precipitate whose composition depends on the synthesis conditions (type of reagents, temperature and pH of the reaction environment, maturing time, etc.). After drying, the powder obtained can be shaped via various ceramic processes: stereolithography, microstereolithography, foam impregnation, microextrusion, etc.
