A process for the manufacture of nanoporous bioceramic bodies for bone implantation, drug delivery and tissue engineering applications

摘要

This invention relates to a process for the preparation of nanoporous bioceramic bodies comprising adding ammonium dihydrogen phosphate to ammoniated calcium nitrate to obtain a precipitate of hydroxyapatite (HAP), preparing a slurry of HAP in water and separately preparing a binder solution in water, adding the binder solution to HAP slurry, followed by spray drying the slurry to obtain microspheres, which are compacted and sintered to obtain the bioceramic bodies.
