Abstract
A method for preparing a hydroxyapatite composite is disclosed. This method comprises alternately soaking a matrix which has been made hydrophilic at least on its surface, in a calcium ion aqueous solution containing calcium ions and substantially free of phosphate ions and in a phosphate ion aqueous solution containing phosphate ions and substantially free of calcium ions to securely form hydroxyapatite at least on the surface of the matrix. Also disclosed is a biocompatible material composed of the hydroxyapatite composite obtained by the method.
